Wondered if anyone else has this. I've just seen the doctor to explain that I'm now being sick when I have my period and also around ovulation time. It's not like being sick normally eg bringing up food , but more like vomiting water/ acid. She asked me if I took ibuprofen , I said yes. I'm now on pills for a month 20mg omeprazole to help me, for a stomach ulcer! I've also had a blood test to check my liver function. I feel bad because when I'm in so much pain I would take ANYTHING to stop the pain , I thought the these were a good choice to reduce inflammation. Anyone heard about this before?
