I was on the depo provera shot for 3 years. My last shot was in September of this year. I did not have a period the entire time I was on the shot. I am now on the Ortho Evra birth control patch. I'm on the off week. Where you don't wear a patch. I have very achy cramps in my lower abdomen. I had unprotected sex with my husband and I feel like I could be pregnant. We were planning on having a baby, but wanted to get pregnant closer to March. I'm just curious if these sound more like implantation cramps, or period cramps. My legs don't hurt like the usually did when I got my period, and my ovaries are fine (they usually stick due to enormous cysts I have on my left side), which is unusual.
