Failed IVF?

QQ

I got 2 embryos transferred on Aug 9. No symptoms at all. I got bleeding today. It doesn’t look like implantation bleeding. So sad...

I have no any blastocyst survived so have to start all trigger shots and retrieval again...

I have another question. I don’t think period should come while taking Endometrin. Am I wrong? Anyone has a similar experience?

Hope baby dust to you all.
