Thanks Ladies, seems that you were all right. My husband spoke to the doctor (I know how ridiculous this sounds, him and not me talking to the doc). Anyway, my estrogen level is low which indicates that I'm entering the meno, although the FSH was normal. So they want to test again to see what the numbers are and then possibly talk to me about starting HRT. Doc said thyroid often comes back inconclusive and this is nothing to be concerned about. I'm going to retest in a couple of months. Doc reckons I could be irregular now and symptomatic for at least another 3 years before they finish completely, but I think I've got maybe another year at the most, as it has all been very sudden and quick. Anyway, you're a wonderful group of women that have helped me dearly and I will keep posting when I get scared or worried and need some support xx
