hi, welcome to BB!
that is a decision only you can really make. but we tf 2 each time. we had 6 embryos tf over 2 cycles. only 1 stuck resulting in my DD.
for me I felt it increased our odds and if we did get twins it would have been less stress for me in terms of not needing to do ivf afain or atleast being happy to leave it for a few years. does yhat make sense?
im personally uncomfortable with only having one child, and itching togetback into it to have a second.
I don't know how that helps you but it really in a personal decision.
