Ok so of course im on birth control have been taking it for over a year and a half or more now and take it at the same time each and everyday, i did drink some alchol not to much just the past view days for celebrations and it was our wedding party so we had a great and fun night as well if you know what i mean. anyways the past two times when i'm getting ready to start my period my boobs have been alittle tender, this was going on before i started taking the pill so i was wondering why all of a sudden this is going on again, is it because of the caffine, weight, stress, i have nooo idea or is it that i need to get a different type of birth control, "i hope not" please please help me understand because I will need to use another form of birth control if its not to late.
