Hello, I had my levels tested via Hertility and all were in normal range apart from my oestradiol level which came back as low - 48.7 pmol/l oestradiol. Google says this is very low for a pre-menopausal woman still having regular periods. I have recently undergone appointments at Aberdeen hospital and after tests & a Hycosy they diagnosed me with "unexplained infertility". They never mentioned that by oestradiol levels were so low at the Aberdeen clinic (nhs) but Hertility picked it up, should I be concerned this is the reason for 2 years infertility?
