I lost my virginity two (2) months ago and I don't know if it's just paranoia but I keep thinking I'm pregnant. We used protection. We did it on the 17th and my period was due the 23rd instead it came on the 21st. It was a normal flow and it lasted normal 5-7 days. Each month after it came as usual but I just keep thinking that I'm pregnant. The last day of my period last month I got back pain that lasted for a few hours but then went and never came back but I don't ever get back pain as a period symptom. My stomach isn't growing or anything but I just wanted to know if I can get my periods for three months after and still be pregnant or if I'm just being paranoid?
