I had a miscarriage in march and got my depo shot as soon as i was able, its June now, and we always have unprotected sex... Every time i eat i want to throw up (nausea), random head aces or light headedness, also i have been on my period for 2 weeks now. I get really bad cramps...he says its the shot making me feel like this could that be true or am i pregnant againn? Im worried
