Can wrong embryo transfer timing affect implantation?

[Nenad]

Hi everyone, grateful if someone can give me words of wisdom. I’ve just had a bfn but also wondering if the clinic may have given me the wrong protocol. I know we’re meant to trust our clinics but I really am wondering this time.

It was a modified natural FET, I was scanned day 12 and asked to do the trigger on the same day and come back in 4 days later for the transfer (cycle day 16). It all felt too rushed but I didn’t say anything because I wanted to trust the clinic. The correct timing I’ve always been told is 5-7 days after trigger, and my transfer was 4 days after for a 5-day blastocyst.

Grateful for any views, whether I have any grounds to make a complaint or if there are actually any success stories coming out of a protocol like the one I was given (4 days after trigger). I’m going out of my mind

Thanks in advance for any insight xx
