Hi am a guy who is 15 and my gf is 16.my girlfriend is complaining of cramps and she told me she that she is 1week and 5 days late (she has a irregular period). she is getting cramps but no blood so. last month she had her period and we had sex like a 3 week before that so i know she wasn't pregnant but is there a possibility? because she is complaining of cramps but no blood sooo..? Am kinda paranoid about this whole situation and idk if she is pregnant or not. Of it could be that we are both just stressing ourselves out .. What do you guys think please help. Any advice?
