Hi farmgirl,
I am relatively young too, 32, and was initially recommended by FS to only do 1. With the stats showing younger women have a higher success rate, I think they like to be conservative at the start. I am like you, desperately wanting a BFP and not minding if it results in twins. I have had two FETs, the first with one embie, the second with two, both of which didn't take and in the future I will always go for two. Feels like I am doing more.

Good luck with what ever you decide.
