For the last three cycles I've been getting headaches and nausea during ovulation, and this cycle it's happening during my period too (period started today). It's never been like this before. I'm not on any hormonal contraception and haven't been for a long time, as I didn't get on with them. I had a baby a year ago, and my periods started up again when he was five weeks old, even though I was breastfeeding (still am once or twice a day). Painkillers don't really touch it and I don't want to be on them all the time anyway. Any ideas?
