I took a Depo-Provera shot 4 months ago, and when i took my pregnancy test it came negative. Then when I got my first shot, I came back 3 months later for my second shot i tok another pregnancy test it came out positive. I found out that day i was 4 months pregnant. I'm worried that the shot may have done harm to my baby. What are the effects to my baby from getting the depo-provera shot while i am pregnant.
