Does anyone else suffer from severe headaches when they are due on? I've only had this since I had my 2nd child (now 18 months). It feels like someone is squeezing my skull and makes me feel sick and generally unwell. It lasts for about 3 days and calms down when I get my period. Does anyone else get this? I appreciate this isn't the worst period related problem out there so I shouldn't complain really. Just wondered how common this is?
