depends when the doctor will do one and if they will do one. Most doctors wont do one just to find out sex of baby. Some due just depends on the doctor. I didn't find out with my oldest until I was 8 months and that was still 50/50 cause she kept moving around and crossing her legs lol. The only reason I found out with mine was cause my dr couldn't find the babys heart beat. I only had 3 done with her, one to make sure how far along I was at 6 or 8 weeks. Another was cause he couldn't find the baby's heart rate at 5 months and the other at 8 months cause he couldn't find it again.
Baby number 2 I had a diffrent dr he had the machine right there in his room so he done them when ever he felt like doing them. I had like 10 with this one lol. He checked to see how far along I was at 20 weeks and he told me it was 100% girl lol my sister had the same dr he said at 20 weeks 100% boy for her he was right both times lol
