Has anyone waited till birth to find out?

Cheyenne
I really want to wait till our baby is born to find out the sex however my husband and everyone else thinks we shouldn't. This is baby number 2 so I wanted a new experience this time around. However I have been curious if the "Ramzi" method is pretty accurate so I've been reading on it however I still don't know what we could be having. Any guesses? 10w3days in this vaginal
