FET next year question regarding blastocysts

[K2012]

Good afternoon ladies need some advice

I had successful IVF/ICSI treatment last year which resulted in a baby boy who’s now 3 months. I’m hoping to do a FET next year before I get too old (turning 38 next month)
I have 2 blastocysts in the freezer, one grade 3Aa and one grade 5Aa, I don’t really know if they’re good embryos?

Should I consider asking the clinic to transfer both of them at the same time to have a higher chance of pregnancy or..? Any other advice on FET/anyt tips etc.

Thank you in advance 👍🏻

@K2012 Their grading is great. I'm currently cautiously optimistic and pregnant 8+2 with a 3BA which is lower grade than both of yours. I also had a fresh transfer and FER are statistically more successful as your body has not been under pressure.
It's up to you would you be happy with Twins?
If not then do 2 single transfers.

Good Luck and congratulations on your baby boy x
