Hi, everyone... I started taking Yaz birth control pill roughly a month ago after my period, it takes about 7 days to kick in and on that seventh day I had unprotected sex. My boyfriend pulled out but I am worried due to the fact, I've taken 2/4 sugar pill and still no period. Ive read similar situations in which periods have been messed up specifically with this type of birth control method. Is it possible that I can be pregnant?

You will have to ask your prescribing doctor about this. Yaz can cause some very weird side effects.
