I just wondered if anyone has had this before. My DH and I have been ttc and this cycle has been unsuccessful. My AF arrived this morning with a bang, I nearly threw up and fainted at work and have actually been sent home unwell. It's much heavier than my normal yet bang on time as it usually would be. Is there something that ttc can do to mess with your period (other than pregnancy obviously) or am I just having a freak month for no reason?
