Hi Ladies, I am currently on my 1st FET HRT cycle after a failed IVF/ISCI in June. Hoping to have some good results from the one and only blastocyst embryo left in freeze.

Last Thursday, during my CD11 BT/US, it was found that my oestrogen level is low at 800 and hence had Progynova dose doubled since then. Endo lining was said to be good at 10.1mm on that day. Was told that FET date is most likely to be on my CD22.

Today, had my CD16 BT/US and was just advised by nurse that I will be needing another round of BT/US on my DC18 though oestrogen level is now at 2100 and endo lining had also increased to 11.5mm.

Am very concerned that my FET date had been kept pushing backward. Is this normal? I thought FET date should not be too far from my last treatment (ie, CD19).

Did ask nurse what exactly are they looking for on my next BT/US before deciding on a FET date but nurse advised that I'll need at least a course of 5 days Progesterone pessaries after my CD18 and hence FET date is most likely to be on my CD24.

Am anxious and unsettled and hope to hear from anyone who could help shed some light on my circumstance, please.

Thank you.
