So I'm coming on here trying to find some answers for my girlfriend. We have been dating for almost 2 years and I care for her very much and we are always very careful when having sex. She is not on the pill and I always use a condom and always pull out before n e ways and always check before and after for rips. She had her last period in the end of December during her winter break from college. Her period has always been kinda everywhere, a few days late here or there, anywhere from 2-7 days late. She was on her roommates cycle before winter break and then she went home for a month and then went back to school with her roommate. She is also very skinny, very little body fat and she runs atleast 3-4 times a week and is alWays busy with school. She had like a 2 week period of being stressed from school the end of February and she recently just went to England for a week and just returned. She said she doesn't think she is pregnant bc if she was "she would b able to tell something is wrong" she is going to take a test Friday but I was hoping to get some advice from ppl who actually experience and know more about periods then I do aka women ha. Please give me any input on the matter asap it would b greatly appreciated. Thanks
