I was diagnosed with PCOS in October and TTC for six months. I have been on Metformin for one month. I thought that my body was finally used to it but the last few days I've been nauseous and today I vomited my insides out. I took a test and it was negative. I don't see how I can do this long term. Any alternatives to Metformin? If not, anything I can take that will help with nausea? Any foods I should stay away from? Any advice? I'm feeling desperate at this point.
