I received my PCOS diagnosis a week ago, and will not be starting BC or Metformin for three more weeks (waiting until after other medical procedures are done). I've been dealing with random bouts of nausea for a long time, but they have been getting worse. There is no chance that I am pregnant. Does anyone else experience nausea/ vomiting from PCOS? Did starting medication help? I have some prescription anti- nausea meds, but i can only take them when its really bad since they cause constipation after a couple doses. What helped with your nausea?
