i misscarried in october and after tests just before christmas i found out the beginning of jan that i have pcos i started metforming 500mg a week ago and they told me i was to up the dose this week to 1000mg and then next week i up it to 1500mg. im just a little confused if what im feeling is to do with the metformin or if its sumthing else. i have got really sore boobs and nipples i am being sick in the mornings and when it comes 2 eating some food i end up gagging and i gag at other things aswell i have had a bad back now for about 5 weeks so i know thats nothing 2 do with it i have also been feeling really emotional one min im ok the next im crying at the smallest thing. are these just side effects of metforming or not im just looking for a few answers b4 i do a preg test. has any1 else experienced any kind of side effects like these
