Soooo I finished my last period on March 12, which is also when I stopped taking my birth control (I'm on the pill, and I just forgot about taking it). Well it's been almost two months, about a month and a half I guess, and I haven't started my period yet. The whole time I was on the BC, except for a couple days, I was bleeding. I took two tests last week, and both were negative. I just don't really know what's going on.
