I've been on the pill for 2 or 3 years and I've always had a regular period since I started taking it, once a month, same exact time every month. But this month, I'm two weeks early. I have not had sex in 3 or 4 months, since my boyfriend and I broke up, and it's been regular every month before this. I did miss a couple pills and I took them later. I know I am not protected for another 1 or 2 weeks until I get back on track, that part I know, but I do not know if that might be causing my "period" to come early or not, or if it really is my period. Any help would be great!
