okay, I have been on Depo for 5 months now, I got my period once the week before my second shot and have had no bleeding since or even before since my first shot. my boyfriend and I never use condoms and never have. for the first time since I've been on any form of birth control I have nearly all the symptoms of pregnancy, I didn't have them on the pill and they didn't start until about 4 weeks after I last had sex (which is about a month after my second shot) and for the last 3-4 weeks now I've been extremely nauseous, bloated, have headaches, all over body aches, I'm really tired, and I've been having stomach cramping and even acid reflux. any opinions?
