BFN 3rd cycle/4th embryo transfer.
I had successful IVF in 2017 long protocol, 2 embryos, transferred day 2 and had a baby boy. No add ons- NHS standard treatment.
Since then we've had a further 3 rounds with no success. Each has been a long protocol. One cycle no embryos one we had three last we had one. I'm 34, low AMH, using donor sperm. I have paid for another cycle but don't know what else to try. The last few transfers we usd lubion as my progesterone was low. This round we did testosterone priming (before that we used DHEA) and clexane after transfer, one time we tried embryo glue.
Any advice? perhaps we need to try a different donor?
