Sorry @seven201 I forgot to mention your sister as well, bless her. I hope she's doing ok in such a tough situation. And hope all your family is ok as well, how stressful for everyone involved ❤️
@whatcangowrong not many people believe in the immune theories, to date it is the least evidence based area of infertility treatment. I went to Coventry as there are two professors there that take a research based approach to it. My results will likely be included in future papers and I thought at the very least contributing to the evidence base would make it worth it.
The microflora has an ok evidence base to it. Yeah it could be better, however studies tend to show the same thing, that microflora is important. Also we're talking about treatment in the form of antibiotics and probiotics, ie not invasive and unlikely to result in harm.
The ERA can be a more touchy area, some studies show there is variability and repeat biopsy can show inconsistent results. I guess mine was kind of like that as the lab assured me the window they suggested would like result in a receptive result, but my repeat showed I was prereceptive at this timing. I guess I'm a bit confused with it, embryos tend to do well in the uterine environment, this is why day 3 embryos are transferred in if there is a risk they may not go on to become day 5 embryos, so surely the embryo can hang about for at least a bit for the endometrium to become responsive? I've also heard of people that have had 2 embryos transferred which are different ages (a day 5 and day 6) and both have implanted. I think the receptive window length may vary I think from a few hours up to 48 hours.
Aspirin and heparin have a pretty limited evidence base to them as well. Even with conditions like antiphospholipid syndrome. In my case it was recommended as I have a c4m2 mutation and 1 abnormally PAI gene. I know some clinics prescribe aspirin and heparin prophylactically so I was fine with adding it in. I wouldn't add it in without discussing with your specialist, firstly it needs to be at the right time, so I take aspirin until 2 days before the transfer and then heparin from the day of transfer. Also your medication may be the incorrect dose and it may be expired.
If your interested in these topics, this is the book I read https://www.amazon.co.uk/dp/B07M6ZF15F/ref=cmswwrcppapiglttSJFGBARZXSK7J43AVDJS?encoding=UTF8&psc=1 some parts are pretty heavy, but you can dip into relevant chapters and get a good idea of the evidence base.
I have 4 euploid embryos left at the moment, the transfer will probably be in just over 3 weeks. I guess I will then try and collect my thoughts when the outcome is known. I just worry that my microflora issues aren't fixable and if there is some unknown reason why embryos never implant in me that isn't related to this, then is there is any point in carrying on.
