Gender surprise & kind of regretting it

I am currently 21 weeks and still don’t know the sex of my baby. I do want to wait to be surprised at the birth, as I truly believe it will be worth it, but I feel it’s made it more difficult to bond and get excited. I’m also so stressed about names. I guess I just feel if I knew the sex I would be able to concentrate on one gendered name and start to connect and get exited.
