Things are definitely not cut and dried, Moosh. I was also told I would find it difficult, and maybe impossible, to conceive ... but managed it at 38, despite being on the Pill at the time!
Gynae has said that my best course of action, given that Norethisterone turns me psychotic and I don't want a Mirena (I don't want it even more since I found out that the hormone it uses is also Norethisterone!) is endometrial ablation by something called Novasure ... which is an alternative to hysterectomy which basically blasts the lining of the womb into oblivion! The consultant didn't tell me much about it (including the fact that it rules out the chances of having more children - although at nearly 45 perhaps he thought I was past it anyway ) Have Googled and frightened myself stupid.
But enough of such frivolities. Am off to collect the weights and will post them in a minute.
