Hi, about 9 days ago I had unprotected sex a couple of times with the pull out method. I just got my second shot of depo provera two days after that, so I believe I've been used to the depo by now. Latethe for the past few days I've had horrible abdominal pains that makes me feel very sore. And I've been dizzy abit, and I got some light brown/pink discharge yesterday, which happens to be the day before my period should start. I had sex the day after my period (period lasted 20 days, so my cycles a little off, so I don't know when I should be starting again!) and I'm very worried I may be pregnant. Help? Sorry for the long description!
