me and my gf have unprotected sex every once in awhile, but all other times i use a condom and i never bust inside her even w/ a condom on. im worried she might be prego, shes been gaining alittle bit of weight...but hey its summer and she hasnt gotten any excersize, this is one of the last things on my list. but shes been complaining about some UTI kinda symptoms (frequent peeing, burning when peeing) i know neither me or her has any STD's because i was her 1st, and im 100% sure i dont have any. shes been saying she feels like utter shit alot of the time, and normally her periods last around 5-6 days, but now they are lasting about 3-4, and shes been bleeding alot less then normally. im headed off to buy some prego tests today, but i figured id ask here because shes in class right now. what really throws me off is that she is getting her periods every month, although i know you can still be prego and get periods.there is a chance obviously that she could be pregnant, but what are the chances that these things could be a sign of pregnancy.
