Hi, I have PCOS and was given Metformin to try to regulate my periods. I started it the first week of jan, I hadnt had a period since december, Would it be possible to be pregnant after taking metformin for just the one month? For 4 days Ive been dizzy all day, having hot flashes, and thicker white discharge. I took a preganancy test 4 days ago that was negative but since i dont have regular periods I wouldnt even be able to tell if I was late or not. So is pregnancy a possibility still?
