I am loosing all hope and really don’t know what to do next.
We had a second FET last Sunday with a single PGS tested hatching embryo and the first response test today is absolutely negative. With our first IVF, positive started to show 5dp5dt but it ended in a chemical. As I always have some fluids in the womb at the beginning of the cycle (they disappear around ovulation time) before this second FET we did a hysteroscopy which showed everything was normal, absolutely nothing found. In this FET fluid disappeared from around day 13 and there were no fluids on transfer day. The doctor also asked us to do thrombophilia screening which again was normal and NK cells tests for both uterus and blood. NK cells in the womb were normal but the blood ones were slightly raised so we did intralipids a few days before the transfer. Because of the chemical pregnancy with the previous cycle, the doctor ruled out the need for ERA as apparently the chemical showed that the embryo transfer timings are right. This was a natural FET supported with cyclogest and also blood thinners injections (just in case said the doctor). The endometrium was over 10mm. On the day after transfer my progesterone was low (42) so they added lubion twice a day and when they checked yesterday (day 5) progesterone was at 284. I feel like there is nothing else left to do and that we have already no hope left at the age of 35. I have low AMH but we are doing IVF because of MFI. I only got pregnant naturally once with twins but it ended in a missed miscarriage at around 8 weeks. We still have 4 pgs tested embryos (day 5 and day 6), but I really don’t know what could be different if we tried FET again. I have bombarded my body with medicines and tests and spent so much money but nothing works. Am I missing anything ?
