Sallyyy - what a rough time you are having
Would you consider having a Mirena fitted? This would protect your womb lining and probably stop, or at least, control the erratic bleeding you are getting. The Mirena is a favourite with many gynaes because it can shrink fibroids and prevent all kinds of problematic bleeding. The other plus of having the Mirena is that it can be a good option as part of an HRT regime - so if you start to get meno symptoms, you simply add oestrogen as pills, patch or gel and you can use as little or as much oestrogen as you need to control flushes etc. So basically it give minimal hassle with a lot of benefits.
You have so much on your plate, so coping with heavy and prolonged bleeding ( which can be typical in peri meno) is the last thing you need right now. I hope things settle soon. DG x
