I recently got on the depo shot, but I didn't get the shot until 4-5 days after my period was over. My boyfriend and I started having unprotected sex again the same day. It has been about 3weeks ago. I am having bad dizzy spells, nausea ( worse at night), very tender and sore breasts ( so bad that I have to wear a sports bra) and now I'm getting bloated and my lower abdomen is slightly crampy, not very bad though.... I am 26 years old, I have a 6 year old daughter, and had a miscarriage at 5 months in September. Could I be pregnant or does it sound like something else? I have never shown up positive on a test until 6 weeks, and I am on phyc medications that I need to stop taking if I am. Please help.
