Endometrin scratch for IVF?

Anyone did hysteroscopy and Endometrin scratch in IVF?

I did two rounds of IVF 1st transferred 1 embryo and 2nd 2 embryos but i lost both very early,

I applied to do PGS test, still waiting for approval, but also my doctor told me we can do the Endometrin scratch on the next round,

If I didn’t get approval for the PGS test I’ll still have to do another round and see my chances

I want to know how was your experience with it, and was it painful? Did it increase your chances?

Do you recommend something else i can ask my doctor about?

I’m really hoping my next pregnancy works and stay healthy 💔💔
