"i&#039;m on the third shot of depo-provera. i have no more periods but the side effects right now are horrible. i have headaches, my stomach is hurting painfully most of my time. i&#039;ve been having hot flashes. i did get dizzy yesterday. but i haven&#039;t gained any weight, in fact i&#039;ve lost 5 pounds but my only concern is my stomach pain, it gives me nausea. i never vomit i only feel like it. it&#039;s huge cramping, and sometimes bloating."
