Does the DEPO shot cause you to vomit at all?

I'm not too sure if it is the shot that makes you puke or what. But I know as personal experience that I have been puking every morning and night, not in between; just nauseousness. I had unprotected sex about a week before I got on depo shot. But I don't believe he came in me. I'm not too sure though, but that's just my out look on the shot.

I started the shot on 11-18-09. Today is 11-27-09.
