Any success with non AA euploids?

Just had our first failed FET with a day 7 6BB euploid. I know day 7s can have lower implantation rates… but our remaining euploids are day 6s and are a 5CC and 3CC. I have excised stage 1 endometriosis within the last year which unfortunately blocked my tubes. We don’t have any other fertility issues aside from that.

I know having euploids is what matters, but after having a failed transfer with our highest graded embryo, I’m very discouraged.
