Hi, Four years ago, I miscarried and since then I am have been diagnosed with PCOS. I have been on metformin for 3 years, and am currently 5 1/2 weeks pregnant with the first (Patience is a virtue!) While pregnant, I have been having some bleeding and cramping, which of course nothing can be seen with the baby because I am early. I have had my HCG checked which is showing that everything is on target, but I was wondering if anyone had these same side effects being pregnant and on metformin?
