With DS I didn't find out and was happy to wait.
With this pregnancy, because I have PND (with history of severe depression and anxiety) and it was a very unexpected BFP, my support team suggested finding out the sex of bub - because I didn't know if I could handle having another DS, no connection with the pregnancy, relapse in PND and anxiety etc. However, having found out, it still doesn't make it anymore real to me, but it isn't related to the gender itms

I guess it really comes down to how disappointed would you be if you got a certain outcome?
