My GF was 3 days late on her period last month; she was supposed to get it Feb 24 but got it on Feb 27. We think this has to do with a lot of stress she has had that month. Her period was normal in color and in length it started off heavy went to medium and then light, it lasted 7 days. Also she had her normal symptoms before her period she had her craving for chocolate and she broke out and her breasts got bigger. Now 2 days after she began to see brown which happens at the end of her period but this has happened for a week now and we are just wondering what it could be from. We do not have sex, meaning I do not penetrate her, but I do rub my penis on her vagina. Can someone please reply and let us know what is going on. This has never happened before.
