So this is my 4th pregnancy, my first we miscarried at 20 weeks which we found out was a boy and since have had two successful pregnancies, two sweet girls! This is my last baby and we are waiting to find out the sex till delievery day! My question is the heartbeat- with this one it started out at 8 weeks 180 now at 16 weeks it's 140, my girls never were that low? I am just curious on the gender 😉 going along with the old wives tales! Any guesses?
