Hi Discogirl,
I've had two tests for oestrogen levels. One in January 2021, after 12 months without a period, and one at the beginning of this year. The first one was 586 pmol and the 2nd one 29 pmol. There was a huge drop in the space of a year! I couldn't understand why it was still so high after 12 months without a period because I've never been on HRT.
Sometimes these things don't make sense at all.
