I'm on my first month of Tri Sprintec and I'm a Tuesday starter since I took it on the first day of my period! However I had unprotected sex on the third week. And I had unprotected sex again today and I'm on my 4 white pill. I also have not gotten my period yet. I don't know if I might be pregnant. I also dnt know if it increase my risk since I forgot to take my pill at the usual time, however it was within 24 hours not a day.
If you took a pill daily for the first week starting the first day of your period, the manufacturer claims you are protected against pregnancy after 7 days on the pill. Most docs and clinics tell you to use protection the whole first cycle to be extra safe. If you had unprotected sex the third week you were likely ok as long as you did take a pill each day. It is best to take them at roughly the same time of day but an hour or two either way doesnt make much difference. Once you are protected, you are still protected even during the days of taking the inert or sugar pill during the week for your period. The pill supresses ovulation and if you dont ovulate you wont get pregnant. When you miss a pill, especially more than one pill, there is a chance you could ovulate so that is the reason you are told to use back up for a week in the event of a missed pill. As long as you take a pill every day at roughly the same time of day, you will be protected against pregnancy. As your body is adjusting to the new hormones in the pill, your periods can be a little irregular. Most women start, on average, the third or fourth inert pill. Your period may come yet. On occasion you may not have much period, just some spotting or maybe no period at all. This is ok as long as you havent missed any pills. If you were to miss two periods in a row, you should test for pregnany and see your Dr.
