Skip a period, or skipping your period on Yasmin, tricyclics, and NuvaRing are among the most common terms used by the people who find my site via search engines. So, to help these visitors, as well as my regular readers, I've decided to do a post on the regimens used to skip a menstrual period. This way, you'll have all the information in one place.
Before we start, note:
I. What follows is just an outline of the "skipping your period" (extended) regimens.
II. If you use the Pill, it's best to use a monophasic brand.
TIP: To find out if the brand you're using is monophasic, look at the pack. For a 28-day pack, if 21 pills are the same color and contain the same amount of estrogen and progestin, and 7 pills are a different color and are inactive (placebo), it's a monophasic brand.
Note: The 28-day pack, shortened placebo interval (24/4), brands
Loestrin 24 Fe and
YAZ are monophasics. As are the 84-day pack brand
Lybrel and the 91-day pack brand
Seasonale. The other 91-day pack brand,
Seasonique, is a biphasic.
III. Your menstrual period and withdrawal bleeding are not one and the same thing.
When you use a combination birth control method, like the Pill, you are not skipping a menstrual period. That's because, for as long as you use such a method, you don't have a menstrual period. What you are doing is shifting the frequency of the withdrawal bleeding episode from once a month to once every few months.
The monthly menstrual period and the monthly withdrawal bleed are distinct, unrelated events.
The monthly period is the body-directed shedding of a thickened uterine lining, under the influence of fluctuating endogenous hormone levels, at set intervals (~21 days). The monthly withdrawal bleed is the user-directed artificial destabilization of a thin uterine lining, as a result of deliberately manipulating the dosage of exogenous hormones in the Pill, at arbitrarily set intervals (21 days, 49 days, 84 days, 168 days, or 336 days).
A monthly menstrual period has a [single] biological purpose: to prepare the uterine lining for pregnancy. A monthly withdrawal bleed has no physiological or biological purpose. It's a designer trick, intended mostly to appease politicians and Popes. It's a historical artifact, not a biological requirement.
IV. The most common side effect with an extended regimen is
breakthrough bleeding/spotting (BTB).
V. If you plan to skip your period for a special event, it's best to plan ahead.
Extended regimens work best (less/no BTB) if you plan ahead and give your body at least three months to get used to the new regimen. This applies to both these scenarios: a) you're already using one of the methods on a regular regimen and plan to switch to an extended regimen, or b) you're not using any method and plan to start using an extended regimen.
Of course, it's not always possible to plan ahead. So, if you need to skip your period sooner rather than later, ask your doctor about the high dose, progestin-only regimen (e.g., 5 mg norethindrone acetate, 1-3 times daily). This regimen can be started anywhere from 3 weeks (preferably), to 1 week before the event.
VI. Extended regimens offer the same pregnancy protection as regular regimens.
VII. The .pdf links used in the post are to a method's prescribing information.
VIII. Most of the regimens are based on clinical experience.
IX. Finally, your doctor gives you medical advice, your blogger gives you educational information.
Here are the methods and the regimens.
Yasmin (.pdf) is a combination, monophasic--estrogen (0.03 mg ethinyl estradiol) + progestin (3 mg drospirenone)--birth control pill. All active pills (21 yellow pills) contain the same amount of hormones. The placebo pills, or "sugar" pills (7 white pills) are inert.
Regular regimen: To bleed once a month
Take one active pill [yellow pill for Yasmin] per day for 21 days, followed by one placebo pill [white pill for Yasmin] for 7 days (bleeding). After the last placebo pill start a new pack.
Extended regimen: To bleed once every three months
Take one active pill [yellow pill for Yasmin] per day for 84 days, followed by one placebo pill [white pill for Yasim] for 7 days (bleeding). After the last placebo pill start another 84-day, active pill, cycle. [You'll need four pill packs per cycle for this regimen.]
TIP: To vary the bleeding interval, vary the number of packs you use. For example, to bleed every month and a half you'll need two pill packs. Take one active pill per day for 42 days, followed by one placebo pill per day for 7 days (bleeding). Or, you can start with three pill packs, and take one active pill per day for 63 days, followed by one placebo pill for 7 days (bleeding).
Ortho Tri-Cyclen Lo (.pdf) is a combination,
triphasic--estrogen (0.025 mg ethinyl estradiol) + progestin (0.180 mg/0.215 mg/0.250 mg norgestimate)--birth control pill. All 21 active pills (7 white, 7 light blue, and 7 blue) contain the same amount of estrogen. The amount of progestin varies: the 7 white pills have 0.180 mg; the 7 light blue pills have 0.215mg; and the 7 blue pills have 0.250 mg. The placebo pills, or "sugar" pills (7 green pills) are inert.
Regular regimen: To bleed once a month
Take one active pill [7 white + 7 light blue + 7 blue pills for Orto Tri-Cyclen] per day for 21 days, followed by one placebo pill [green pill for Ortho Tri-Cyclen] for 7 days (bleeding). After the last placebo pill start a new pack.
Extended regimen:
To skip one "period" (or delay the bleeding by one week)
A) Take one active pill [7 white + 7 light blue + 7 blue pills for Orto Tri-Cyclen Lo/Ortho Tri-Cyclen] per day for 21 days. When you get to the 7 placebo pills [green pill for Ortho Tri-Cyclen Lo/Ortho Tri-Cyclen] throw them out and
instead take the third week of active pills from a new pack [7 blue pills for Ortho Tri-Cyclen Lo/Ortho Tri-Cyclen].
Once you're done, either start a new pack right away (skip bleeding) or wait one week and then start a new pack (delays bleeding by one week).
[Pack #1] 7 white pills + 7 light blue pills + 7 blue pills + [Pack #2] 7 blue pills.
Start a new pack right away/Wait one week, then start a new pack.
B) Take one active pill [7 white + 7 light blue + 7 blue pills for Orto Tri-Cyclen Lo/Ortho Tri-Cyclen] per day for 21 days, followed by one placebo pill [green pill for Ortho Tri-Cyclen Lo/Ortho Tri-Cyclen] for 7 days (bleeding). After the last placebo pill wait for one week*; don't take any pills. Then start a new pack and take the 21 active pills, followed by the 7 placebo pills. [This regimen shifts the bleeding episode by one week during the second month.]
*
VERY IMPORTANT: You are not protected against pregnancy during the week you delay taking the next pack. You must use an alternate birth control method (condom, diaphragm, sponge, etc.).
7 white pills + 7 light blue pills + 7 blue pills + 7 green pills.
Wait one week (no pills). [No Pregnancy Protection!]
Start a new pack.
To bleed once every three months
1. Take one active pill [7 white + 7 light blue + 7 blue pills for Orto Tri-Cyclen Lo/Ortho Tri-Cyclen] per day for 21 days. When you get to the 7 placebo pills [green pill for Ortho Tri-Cyclen Lo/Ortho Tri-Cyclen] throw them out and
instead start a new pack. Repeat the regimen with the new pack; use 4 packs total. Stop for one week [either don't take any pills, or take the 7 green pills] (bleeding) then restart.
7 white pills + 7 light blue pills + 7 blue pills.
Start a new pack (take active pills only). Repeat [4 packs total].
Wait one week, then start a new pack.
TIP: To vary the bleeding interval, vary the number of packs you use.
Note: This is the regimen most likely to trigger BTB.
2. Take one active pill [7 white + 7 light blue + 7 blue pills for Orto Tri-Cyclen Lo/Ortho Tri-Cyclen] per day for 21 days. When you get to the 7 placebo pills [green pill for Ortho Tri-Cyclen Lo/Ortho Tri-Cyclen] throw them out. Start a new pack backwards, after first discarding the 7 placebo pills from this new pack [7 blue + 7 light blue + 7 white pills for Orto Tri-Cyclen Lo/Ortho Tri-Cyclen]. Repeat the regimen with the next two packs; use 4 packs total. Stop for one week [either don't take any pills, or take the 7 green pills] (bleeding) then restart.
[Pack #1] 7 white pills + 7 light blue pills +
7 blue pills + [Pack #2]
7 blue pills + 7 light blue pills +
7 white pills + [Pack #3]
7 white pills + 7 light blue pills +
7 blue pills + [Pack #4]
7 blue pills + 7 light blue pills + 7 white pills.
Start a new pack backwards (take active pills only). Repeat [4 packs total].
Wait one week, then start a new pack.
3. Start with three new packs (or two). Take the first 7 active pills [white pills for Ortho Tri-Cyclen Lo/Ortho Tri-Cyclen] from each of the three packs, for a total of 21 pills. Then take the next 7 active pills [light blue for Ortho Tri-Cyclen Lo/Ortho Tri-Cyclen] from each of the three packs, or 21 pills total. Finally, take the last set of 7 active pills [blue pills for Ortho Tri-Cyclen Lo/Ortho Tri-Cyclen] from the three packs, or 21 pills total. Stop for one week [either don't take any pills, or take the 7 green pills] (bleeding) then restart.
[Pack #1] 7 white pills + [Pack #2] 7 white pills + [Pack #3] 7 white pills + [Pack #1] 7 light blue pills + [Pack #2] 7 light blue pills + [Pack #3] 7 light blue pills + [Pack #1] 7 blue pills + [Pack #2] 7 blue pills + [Pack #3] 7 blue pills.
Stop for one week, then restart.
Ortho Evra (.pdf) is a combination--estrogen (0.75 mg ethinyl estradiol) + progestin (6.00 mg norelgestromin)--birth control skin patch. It releases 0.020 mg of estrogen and 0.150 mg of progestin per day.
Regular regimen: To bleed once a month
Apply one patch and leave it on for 1 week. At the end of the week, remove the patch, discard it and replace it with a new patch. Do this for 3 weeks in a row. At the end of the third week, remove and discard the last patch and wait for one week; that's the patch-free week (bleeding). Once the week is over, restart the regular [3 weeks:3 patches on/1 week off] patch regimen.
Extended regimen: To bleed every few months
Apply one patch and leave it on for 1 week. At the end of the week, remove the patch, discard it and replace it with a new patch. Do this for 8 weeks (or
12 weeks) in a row. At the end of the eighth week (or twelfth week), remove and discard the last patch and wait for one week; that's the patch-free week (bleeding). Once the week is over, restart the the extended-use [8 weeks:8 patches (or 12 weeks:12 patches) on/1 week off] patch regimen.
Note: Use of the regular patch regimen [3 weeks:3 patches on/1 week off] entails a 60% higher exposure to estrogen than use of a typical combination Pill brand containing 35 μg of estrogen on a regular regimen [21 days on/7 days off]. Although the
clinical relevance of this finding is unknown, you should be aware of it before starting an extended patch regimen.
NuvaRing (.pdf) is a combination--estrogen (2.7 mg ethinyl estradiol) + progestin (11.7 mg etonogestrel)--birth control vaginal ring. It releases 0.015 mg of estrogen and 0.120 mg of progestin per day.
Regular regimen: To bleed once a month
Insert one ring and leave it in place for 3 weeks in a row. At the end of the third week, remove the ring, discard it and wait for one week; that's the ring-free week (bleeding). Once the week is over, restart the regular [3 weeks on/1 week off] ring regimen.
Extended regimen: To bleed every few months
Insert one ring and leave it in place for 3 weeks in a row. At the end of the third week, remove the ring, discard it and replace it with a new ring right away. Keep the new ring in for 3 weeks in a row. [That's 6 weeks total.] At the end of the third week, remove the ring, discard it and either:
a) wait for one week; that's the ring-free week (bleeding). Once the week is over, restart the extended-use [6 weeks on/1 week off] ring regimen.
b) replace it with a new ring right away. Leave the new ring in place for 3 weeks in a row. At the end of the third week, remove the ring, discard it and replace it with a new ring right away. Keep the new ring in for 3 weeks in a row. [That's 12 weeks total.] At the end of the third week, remove the ring, discard it and wait for one week; that's the ring-free week (bleeding). Once the week is over, restart the extended-use [12 weeks on/1 week off] ring regimen.
TIP: You can also insert one ring and leave it in for 4 weeks in a row, instead of 3 weeks.
[At the end of the fourth week, remove the ring, discard it and replace it with a new ring right away. The rest of the extended regimen is the same as above, except you leave the ring in for 4 weeks, instead of 3 weeks, in a row.]
Note: Use of the regular ring regimen [3 weeks on/1 week off] entails a 50% lower exposure to estrogen than use of a typical combined Pill brand containing 30 μg of estrogen on a regular regimen [21 days on/7 days off]. Although the
clinical relevance of this finding is unknown, you should be aware of it before starting an extended ring regimen.
UPDATE: Right after I finished posting I noticed someone found this by using the search term "
secrets to delaying menstrual period". Heh, there are no secrets. Just information.
ETA: I've updated the post.
