Don't know my gender?

Kimberly
So, I've done all the myth-old wive tale test and all of them said girl, even bought a pee stick that said girl. My baby's last heart rate last month was 152, and I went for a ultrasound at 13 weeks I seen a what looked like a boy, but read that at that early girls and boys both have that same figure. I've also craved lots of sweets and been emotional. And then went to the 3d peanut gallery, at 16 weeks and seen a wee-wee. But I'm still not sure at all because my gut feeling says girl, my heart rate does too, test do, and my syomtoms do. I just dk. We go for a actually doctor ultra sound tmrrw, and I'm 20 weeks today.
