You will not have a menstrual period every month while you are taking an extended-cycle birth control pill. Instead, your period should occur every 12 weeks.
The 91-day birth control pack contains three trays with cards that hold 84 "active" pills and seven "reminder" pills. You must use the pills in a certain order to keep you on a regular cycle.

What happens if I miss a dose?
Missing a pill increases your risk of becoming pregnant.
If you miss one "active" pill, take two pills on the day that you remember. Then take one pill per day for the rest of the pack.
If you miss two "active" pills in a row, take two pills per day for two days in a row. Then take one pill per day for the rest of the pack. Use back-up birth control for at least 7 days following the missed pills.
If you miss three "active" pills in a row, do not take the missed pills. Continue taking 1 pill per day on schedule according to the pill package and leave the missed pills in the package. You may have some bleeding or spotting if you miss three pills in a row. Use back-up birth control for at least the next 7 days.
If you miss any reminder pills, throw them away and keep taking one pill per day until the pack is empty. You do not need back-up birth control if you miss a reminder pill. If your period does not start while you are taking the reminder pills, call your doctor because you might be pregnant.

Seasonique (Levonorgestrel/Ethinyl Estradiol) Dosing Information
Usual Adult Dose for Contraception:
Seasonique (Levonorgestrel/Ethinyl Estradiol) products are packaged in 21, 28 and 91 day dosage preparations.
Regardless of the number of tablets in a package, the cycle length for oral contraceptives is generally considered to be 28 days, except for the 91 day dosage preparation which considers the cycle to be 91 days. (The first day of menstrual bleeding is counted as day 1.) One product (marketed as Lybrel) is supplied in a 28 day package in which all the tablets contain the same active ingredients (no placebo tablets). The tablets are given continuously and gradually reduce or stop menstruation in most women. Thus there is no cycle length with this product.
Initiation of Oral Contraceptive Therapy
This product can be administered in two ways.
When initiating a Sunday start regimen, the first tablet may be taken on the first Sunday after menstruation begins. If a period begins on a Sunday, the first tablet may be taken on that day. When initiating a Sunday start regimen, another contraceptive method should be used until after the first 7 consecutive days of administration. For a 28 day package, one tablet is taken daily for 28 days and a new package begun on the following day. For a 21 day package, one tablet is taken daily for 21 days followed by 7 days with no medication. A new package of contraceptives is begun on the following day. For a 91 day package, one tablet is taken daily for 91 days and a new package begun on the following day. The manufacturer of the 91-day preparation recommends only the Sunday start regimen.
When initiating a Day 1 start regimen, the first tablet is taken on the first day on menstruation. Such initiation may increase the risk of spotting and breakthrough bleeding but decrease the risk of early ovulation and pregnancy. For a 28 day package, one tablet is taken daily for 28 days and a new package begun on the following day. For a 21 day package, one tablet is taken daily for 21 days followed by 7 days with no medication. A new package of contraceptives is begun on the following day.
Many clinicians recommend that additional contraceptive methods be used during the first cycle of hormonal therapy in order to reduce the risk of unintended pregnancy.
If a woman misses one dose of active tablets, the missed dose should be taken as soon as it is remembered and the normal schedule should be resumed.
If a woman misses two doses in week 1 or week 2 of the cycle, 2 tablets may be taken as soon as they are remembered and 2 tablets taken the next day and the normal schedule may be resumed. (Additional contraceptive methods should be used for 7 days.)
If a woman misses two doses in week 3 or three doses at any time in the cycle, Day 1 starters should discard the current package and begin a new package that same day. Sunday starters should take 1 tablet daily from the current package until Sunday, when the current package is discarded and a new package begun. (Additional contraceptive methods should be used until the woman has taken at least 7 days of hormonal therapy from the new package.)
Usual Adult Dose for Postcoital Contraception:
Ethinyl estradiol-levonorgestrel 30 mcg-150 mcg (Levlen or Nordette), 4 tablets no later than 72 hours after having unprotected sex followed by 4 more tablets exactly 12 hours after the first dose.
Ethinyl estradiol-levonorgestrel 30 mcg-125 mcg (Tri-Levlen or Triphasil), 4 tablets no later than 72 hours after having unprotected sex followed by 4 more tablets exactly 12 hours after the first dose. Note that only the phase 3 cycle of these triphasic contraceptives contain sufficient hormone to act as a postcoital contraceptive.
Ethinyl estradiol-levonorgestrel 50 mcg-250 mcg (Preven), 2 tablets no later than 72 hours after having unprotected sex followed by 2 more tablets exactly 12 hours after the first dose.
Patients should be advised to begin therapy at a time that it will make it convenient to take the second dose 12 hours later. Pretreatment with a long acting antinauseant such as meclizine will lessen the incidence of nausea.
What other drugs will affect ethinyl estradiol and levonorgestrel extended-cycle?
The following drugs can make birth control pills less effective, which may result in pregnancy:
- acetaminophen (Tylenol) or ascorbic acid (vitamin C);
- phenylbutazone (Azolid, Butazolidin);
- prednisolone (Orapred);
- theophylline (Respbid, Theo-Dur);
- cyclosporine (Neoral, Sandimmune, Gengraf);
- St. John's wort;
- antibiotics such as amoxicillin (Augmentin), ampicillin (Omnipen), doxycycline (Doryx, Vibramycin), griseofulvin (Grisactin, Grifulvin, Fulvicin), minocycline (Minocin), penicillin (Veetids, Pen Vee K, Bicillin), rifampin (Rifadin), rifabutin (Mycobutin), tetracycline, and others;
- seizure medicines such as phenytoin (Dilantin), carbamazepine (Tegretol), felbamate (Felbatol), oxcarbazepine (Trileptal), topiramate (Topamax), or primidone (Mysoline);
- a barbiturate such as butabarbital (Butisol), mephobarbital (Mebaral), secobarbital (Seconal), or phenobarbital (Luminal, Solfoton); or
- HIV medicines such as indinavir (Crixivan), saquinavir (Invirase), lopinavir/ritonavir (Kaletra), fosamprenavir (Lexiva), ritonavir (Norvir), or nelfinavir (Viracept), and others.
This list is not complete and there may be other drugs that can interact with birth control pills. Tell your doctor about all the prescription and over-the-counter medications you use. This includes vitamins, minerals, herbal products, and drugs prescribed by other doctors. Do not start using a new medication without telling your doctor.
