I missed two pills in a row and didn't make them up, I  had unprotected sex and Immediately after started bleeding which lasted about a day. It was only a week after my "period"/ withdrawal bleed(like normal 4 day flow) so it wasn't that, it was just bleeding because I missed pills. Is it possible that I ovulated during that time even though I bled? I'm asking because a week after that I had brown discharge and spotting and now am getting pregnancy symptoms. Should I be worried even though I was bleeding when I had sex because breakthrough bleeding means the pill isn't working because I missed it right..?
