Anyone with similar numbers?

Tuli • 39yo. Pregnant after 1st FET. Ttc since 05/16. 2 iui, 2nd ended in chemical. Cervical stenosis after lletz

I had my egg retrieval last Wednesday, although I had 22 follicles we only had 16 mature eggs. 11 fertilised but only 3 made it to day 5 freeze (graded 4ab, 4bb and 3bb) the rest were kept for day six but were discarded after all.

I feel really discouraged.

Anyone has any insight to why? Or had a similar journey? Was your FET successful?
