text: on birth control pill and skipped a period? ok, i have been on birth control (ortho tricylen lo) for 2 months now. this month, i have not gotten my period yet. i have taken the pill around the same time (4:00) daily, give or take 2 or 3 hours depending on my schedual that day.  my boyfriend uses the withdraw method, and has only 'come' in me once, consequently, it was right after my last period and on the day i started my new pack.  now, i am not on my period, but have no other pregnancy signs, and i have a slight brown discharge, and feel as though i am going to get my period ... could i be pregnant? or, is this just a side affect of being on birth control for the first time? that is a very common reaction to birth control. i wouldn't worry too much unless you really think you are pregnant. of course it's always best to be cautious; for $10 a pregnancy test wouldn't hurt.
