I wondered if you could help... We have severe male factor as a fertility problem so we're very clued up on what to do for that. The problem is that my cycle seems to have suddenly changed for no reason. I'm usually on a 28-31 day cycle, have been for years. Then I had on of 26 days and now one of 20 days! I know stress can play a part in that, but I've just been on a weeks holidya to the sea so I'm actually rather relaxed! Does this mean there is now a problem with me? Could anyone give me a clue why this is happening? Thanks.
