Hi all, sorry, it's me again.I've had 4 failed fresh cycles last year (1 single and three double transfers). I think the main reason that these have failed is due to embryo quality. Some of the transfers were early blastocysts/ morulas and they weren't top grade.
However my consultant has suggested that as a next step tests for failed implantation would be recommended, followed by transferring my 2 frozen embryos and then if they fail going to donor eggs. That is not my preference as I feel time is ticking and want to give my eggs a go. My understanding is that a minority are viable and it's about fishing them out in multiple cycles and relying on luck, with the understanding chances are getting ever slimmer.
We agreed I'd do another 1 or 2 fresh cycles with my own eggs. I don't feel I can give up yet as my AMH, egg numbers, lining etc are great. My issue is with poor development and I only get a max of 2-3 blasts on day 5 or 6.
For context, I am trying for a sibling after success getting pregnant at 41 with a day 6 blastocyst and giving birth at 42.
The tests for failed implantation suggested are
(i) testing for sticky syndrome called antiphospholipid syndrome.
I'm not sure if this is relevant given that I've had no chemical pregnancies or miscarriages.
Treatment is Aspirin or Heparin. I am told that Aspirin shouldn't be taken without the rest as it may cause harm. This seems controversial as my clinic in Greece prescribed mini aspirin in any case.
Even if this test is positive, it would need to be repeated so takes an additional 10-12 weeks
(ii) Endometrial Trio (which I think includes ERA)
This would involve taking medication for a cycle with no collection or transfer so would be a time delay. From what I've read, there is no strong evidence for it and the adjusted timing for transfer may be detrimental in some cases
(ii) Uterine natural killer cell testing in Coventry with Prof Selby
Ultimately I think the most probable reason for my cycle fails is egg quality rather than issues which might be found with any of these tests. Also, since I've had a successful pregnancy, are NK killer cells something that might be relevant for one cycle and not another or a developed condition?
Thoughts and experiences much appreciated xx
