I had my period about 10 days ago. I take birth control regularly (except for the occasional one or two pills a month that I miss). I woke up this morning and I have blood in my underwear like I just started my period again. It's not a little spotting.. It's enough to have to put a tampon in. I missed two BC pills yesterday and the day before. Do you think maybe my body is thinking I should be on my period since I skipped the two pills?
