For the last few months I have noticed nausea and feeling really off a couple of days before my period. This month the nausea 2 days before wss awful to the point I thought I was coming down with a stomach bug. It comes on as hot flashes and my cheeks and chest feel warm and flushed. I finished my period yesterday and today feel exactly the same and needing to poo a lot but its not diarrhoea. I am 35.
