Is it possible to miss your period when on birth control (tri-sprintec)? I have been taking it for about 2 years. About two months ago, I missed the full week of my placebo pills and I am wondering if that has anything to do with it. I also took two prenancy tests, one being in the morning after I just woke up, and they were bth negative.
Welcome to ehealthforum,
The placebo pills (as the name suggests) do not contain any hormones and hence, taking them or not taking them does not make much difference as long as you start your next birth control pill pack at the scheduled time. If you had been regular with taking the active pills at scheduled time daily, you should remain protected. It is also considered normal to miss 1-2 periods while being on prolonged use of hormonal contraceptive pill use. If you are worried about pregnancy, always use back-up protection while having intercourse for additional protection from pregnancy. Visit your doctor/gynecologist for further clarification and assistance.
