Hello all, gosh so much to catch up on. Will get my usual rambling essay over with to update you on the latest with my toxic uterus, then get the me me me out the way so I can reply properly to you all.
Had our WTF appt with my Dr yesterday. He was really sad for us about the outcome of this cycle, but didn't think I was a lost cause. He said I did propagate a pregnancy before (albeit one with sudden foetal demise) and we need to get me back to that place. If I hadn't been properly pregnant before, we might be in a different situation. But that gives him hope. He was really apologetic - we said well the facts are the facts, it's no one's fault and there's no sense in sugar coating it. And he said 'yes, but you're nice people and you've been through a hell of a lot, and I really want this to work for you!'. So we have someone batting for us really hard.
He said something definitely did implant and start to invade the endometrium, it wasn't failed implantation, it was a very early miscarriage - but as far as he's concerned the issue definitely lies with the endometrium and its ability to support a pregnancy (which I agree with). He said we've got the embryos and they're not going anywhere. So the plan is to work on my lining over the next few months.
Hysteroscopy is confirmed for Weds, but will thankfully be less of a D&C (and more of a light clean and polish) as amazingly, there's no crap left in my uterus, despite not having had a proper period (yes, apparently you can absorb uterine lining).
Copper IUD goes in on Weds when he's doing the hysto, and we do one month of HRT and see if I get a bleed. Probably repeat again then take IUD out. The copper generates an inflammatory reaction which causes the endometrium to thicken - it's why women who get a copper coil tend to have very heavy periods. So the copper IUD is used in cases of Ashermans syndrome (even if that's not what I have, we're treating me as if I do) to kick the lining into gear and restore menstruation.
Then we will do a mock FET. We'll do endometrial biopsies to see what the lining is actually doing from a histology POV, not just what the scan says it's doing - one in the first half of the cycle in the proliferative phase, then after starting progesterone he's recommended we do the ERA biopsy (the one which looks at the lining during the implantation window to see how receptive it is).
Depending on how they go, whether we have to try different combinations of FET drugs if I still don't respond well to oestrogen (eg Tamoxifen), maybe a few months down the line we could be in a position to actually do a treatment cycle for real and put one of our PGS tested frozen embryos back. Until then it's back onto the bench of boredom I go...
The universe has a funny sense of humour that HRT and contraception are supposed to help me to get and stay pregnant 🤔
