text: i have a concern about the pill...? i have been on the pill for about 3 months, and it has been working great, but this month has been weird. every so often i get those menstral cramp feelings, and i bled a little before i was supposed to start my period. is that normal? yes its very normal.  you are on your third month of the pill and your body is still getting used to it.  usually after the third month there are no more problems with the spotting and cramps before the period.  some birth control even reduces your menstrual pain drastically  after the 3rd month.
