@Dreamscometrue, is this going to be your 2nd or 3rd cycle? If you have done 2 blastocysts transfer previously and didn't succeed, usually doc will agree with 2 blastocysts or 3 embryos for subsequent transfers if I'm not mistaken. My first fresh cycle with 2 day-2 embryos transfer failed, from then on, partly due to my age, there wasn't much deliberation on my doc's part to proceed with the max. no. of embryos allowed by law for my subsequent transfers. So for my 1st FET, 2nd & 3rd fresh, we did 3 day-2 embryos each time. All failed to implant but managed to have good no. of frozen embryos from 3rd fresh to try blastocysts. Even tho it was my first blastocyst transfer, but was also my 5th transfer and I was late 38yo then, doc supported going straight for 2 blastocysts and one managed to implant. I agree with feeling that after failing previous cycles with max. no. of embryo transfers everytime with good embies, you just want to up your chances against your odds to get a viable bfp. If you can & are going for blastocysts this time, I would say go for the max. 2. Stay positive & all the best ya
