Im 21 years old, and im currently on the Depo shot, and have had my period for almost a month know, about 2 weeks ago I thought I was done, so I decided to have sex but when we were done I noticed my period wasnt done (sorry) and a week after that I started getting really nauseous in the morning and through out the day, and a butterfly feeling in my stomach, and other symptoms I used to have when I was pregnant with my daughter. Ive done 2 home preg. Test but their negative. If it werent for my period and neg. Tests i would say i was pregnant. I havent been to the doc's yet cuz I have no Insurance. What may be wrong with me? Or has anyone had anything similar happen to them.
