Anyone had nausea and really bad cramps during ovulation?? I havent ovulated yet.. Taking opks. But last two days ive been getting really bad nausea and cramps where all i wanna do is stay in bed lying on my tummy. Last two nights ive had to take anti-nausea pills left over from my last pregnancy just to dull the pain away enough to get some sleep. Any tips?? AF isnt due another two weeks. Not sure what is going on??
