I had a miscarriage two years ago and just recently was told I have PCOS and was put on metformin and it has really helped me get regular. Well I ovulated the 7th and now my nipples are very sore I had heart burn last week the worse I have had I can't eat anything spicey which I love spicey food. Sometimes feel nauseous. Took a test Friday morning and had a faint positive. Took one around lunch time today and negative. Any advice or has anyone went through this before??
