I previously had a blighted ovum and now I am pregnant again (6 weeks 3 days). My doctor ran my progesterone levels and they are a 7.4. The nurse I spoke with stated that they would like for them to be around a 16-20, so they put me on oral supplements (100 mg) twice daily. Of course, after she told me this I googled low progesterone and FREAKED OUT because it looks like that is either a symptom of a pending miscarriage or a cause of miscarriage. She assured me that I would be fine and that we would see a little baby on the ultrasound next week. But now I am freaking out b/c my symptoms seemed to have vanished and now I'm afraid I am having another blighted ovum. HELP!! Anyone else have low progesterone and not miscarry?
