see i found out at 16 weeks with my oldest son and 17 weeks with my baby now.

It's a possibility I almost found out at 14 1/2 weeks but the umbilical cord was in the way and baby wouldn't change its position so now I'll be finding out at 18 weeks which is my next appointment

they may make a guess but not a for sure result because they usually wait till ur 18-22 weeks to be 100 percent sure, unless they do the blood test to find out
