Hi, thanks for your question. If you have missed 3 of the hormone pills, you may get some spotting or bleeding  as the hormone level has lowered. Depending on what part of the pill pack you missed the pills here  is the recommended advice from Alesse. If you still have the paper insert that comes with your pill pack, you may find this advice written there. If you are in British Columbia, you can also call the 1-800-SEX-SENSE line to speak to a nurse with any questions about contraception. 

If you MISS 3 OR MORE pink “active” pills in a row (during the first 3 weeks)
• If you are a Day 1 Starter: THROW OUT the rest of the pill pack and start a new pack that same day.
• If you are a Sunday Starter: Keep taking 1 pill every day until Sunday. On Sunday, THROW OUT the rest of the pack and start a new pack of pills that same day.
• You may not have your period this month but this is expected. However, if you miss your period 2 months in a row, call your health-care provider because you might be pregnant.
• You COULD BECOME PREGNANT if you have sex in the 7 days after you restart your pills. You MUST use a nonhormonal birth-control method (such as condoms or spermicide) as a back-up
• for those 7 days.

If you forget any of the 7 light-green “reminder” pills in Week 4
• THROW AWAY the pills you missed.
• Keep taking 1 pill each day until the pack is empty.
• You do not need a back-up nonhormonal birth-control method if you start your next pack on time.
