Yup! #5 for us too. I have 2 boys and 2 girls as well (aged 6, 4, 2.5, 17 months). This will be a tie breaker for us too (I'm 99% sure we're having a girl though).
My EDD is June 12
How old are your LO's?
Mine are 4, 3, 15 months and 3 months. This was definitely NOT expected and DH has agreed to get a vasectomy when I'm in the third trimester with this baby. I'm prone to losses so we want to make sure everything is going well with this pregnancy because we eventually wanted a tiebreaker... just weren't prepared for it to happen THIS soon LOL! I'm probably going to have a girl too because there are more girls in my family than there are boys but we'll see
