I have regular periods of 28 days. I'm two weeks late for AF and no sign of it arriving. Testing negative since AF due. No PMS or pregnancy symptoms. I just want this cycle to be over so that we can try again. I have no idea why I've missed a period, this has never happened to me before! Would I be crazy to make an appointment with my GP? For anyone who has completely missed a period, did it arrive the next month like normal? Did you ever find out what had happened?
