Hi, the last time I came on my period was march 19, 2012. I missed April and now May. I usually have my period every month on time... I was taking depo but I been stopped depo and they put me on birth control pills but after I missed april I stopped taking it because I think I'm pregnant but I took blood work and pregnancy test and they all come out negative. What to do because I know I'm pregnant, I been having craving, I been feeling like I'm going to throw up but I haven't actually thrown up, back pains, and my stomache has gotten a little bigger than usual.
