Hi. So my friend is having late periods. Like generally her periods start around 1st or 2nd of a month and the gap is of 30 days. The thing is that she got intimate with her boyfriend but they did not have sex so there is no chance of pregnancy. I have been trying to explain her that but she will only be sure and be a bit relaxed if a doctor tells her. I told her its also because of stress and because she has been stressing over it hence it is late. Please help.
