So I posted about 2 weeks ago...I was 1 week late on my period after being fairly regular since August and being on Metformin. So, it's now the end of the first week of March and I still have not had my period. I took a pregnancy last week and my heart broke a little more because it came back negative. I don't want to take another one because I can't handle the sadness right now if and when it comes back negative again. I have PCOS and was told by a friend of mine that women with PCOS should get their pregnancy test results via blood work. Does anyone have any experience with this? Any advice?
