i'm 20 years old, and i just started taking birth control 2 months ago (tri-cyclen lo) last month, i got my period on a friday which was my 6th placebo pill. 5 days ago, me and my boyfriend had unprotected sex and he came in me, while i was still on my hormone pills and i was ovulating. my period is supposed to start in 2 days, but i had some spotting this morning. my underpants were red but when i went to wipe myself, nothing came off of the toilet paper? i put on a pad and usually on my first day there is significant bleeding, but right now there is barely anything. i also have no cramps, no swollen breasts, no bloating, and no weight gain which are all things i usually get just as i'm about to start my period. is this just my body getting used to the pill or is there a chance i could be pregnant? PLEASE HELP!! i have also been taking my birth control everyday at the exact same. (sometimes half an hour later)
