Ok back in early november me and my girlfriend had unprotected sex. We usually NEVER do. But she was on birthcontroll i'm pretty positive i cummed in her but that month she got her period and she has gotten her period all the way up to this month. Although she just got her depo shot the month her period didnt come but i was still worried. So i had her take a pregnancy test it came back negative. But if she were pregnant shed be about 18 weeks. she has had some weight gain but she just recently went to the doctor and she lost a pound so she weighs about 135 but we had to take her to the ER for bad chest pains under her right boob they did not do a pregnancy test on her. She also wasnt given 1 when she got her depo. Usually around her period her in her lower back these two bones will hurt really bad.The doctors have no clue what it is shes had it for years. But ever since she got her depo shot her back has been hurting at least once a week every week. Besides that she hasnt really shown any pregnancy signs expect fatigue mood swings kind of a increased appetite but no throwing up or nausea also she has developed bad itchy eyes over the past couple months and her stomach isnt all that big her boobs do not hurt and they havent gotten any bigger she is not peeing a lot and i asked her if her period was the same flow and she said everything the same. The only thing new is that her stomach has been making these weird noises. when i put my head on it, it just sounds like a fish swimming. Also she said her stomach was being weird that when she fell asleep she fell asleep with her mouth open and that it felt like Traped air. Im just worried and not wanting to be a dad. but do you think shes pregnant?
