I'm 18, and I got my first depo shot Feb.5 2013. So I am supposed to go back in a few days to get me next. Well, my boyfriend and I had intercourse and he didn't finish inside of me, he pulled out, but lately I have had a very rumbly stomach and lower abdominal pains with quite a bit of gas. I've been tanning so I can't tell if my areolas are darker or not. I just need to know what I should do! I do not want a kid right now and I am scared to death.
