Me and my DH have decided TTC DC2 so have just come off cerazette last week. I?ve never had regular periods, and aswell as having PCOS I can never tell when I ovulate! Is there any other way I can tell? Last period I had was the beginning of May. Was 3 years ago when I was last pregnant so I can?t remember much! I?ve had cramps this week, so not sure if that is just coming off the pill symptoms or ovulation? TIA
