Nervous about first transfer

I need some words of encouragement.. out of my 10 eggs we only ended up with one baby that’s on ice right now so we have one shot at this. The thing that is worrying me is that it’s graded a 4BC and I’ve done a lot of research on my own and since I’m under 30 the chances seem good but I need some success stories! I’m so nervous that the baby won’t stick 😕🥺

P.S. I start my provera today because cycle never came. I don’t have my meds protocol yet until I get my cycle and get my first ultrasound

Any tips and tricks that helped? I’ve heard of the pineapple thing but not sure if that really helps or not.
