My first cycle, it took awhile to get me suppressed and when got to retrieval, only got 4 eggs-3 immature and 1 mature. ICSI was used but the one mature egg didn't fertilize. This cycle, it still took awhile to get suppressed and had to have cyst aspirated. Retrieved 12 eggs-5 mature and 3 fertilized. Only 2 made it to transfer (one-8 cell and one-5 cell). Transfer was 7/28 and Beta is 8/8. Hoping for BFP but not very optimistic.
Statistically, the most common answer, by far, should be "Embryos did not implant during 2WW".
Avoid IVF and surrogacy in Ukraine. Ukrainian centers pay shills to post here under numerous sock accounts pretending to be patients in Ukraine. Centers using such deceptive advertising cannot be trusted and should be avoided.
