My girlfriend has missed her period for three months, she s been having occassional sharp pains in her stomach, other times she s had an aching pain. She has had a bit of weight gain. She s had cramps like she is having her period, but no bleeding. But we haven t had penetrative sex for around... 4 months, and I have never ejaculated inside her. We have always been careful to the point of paranoia. Her family has a history of Celiac s disease, and she has had issues with her period since before we were together. Is she pregnant? or am I getting scared for nothing?
