Hi i wanted to figure out from this ultrasound if i am indeed having a boy. my ob seems positive, but i just want to make sure ? it looks like the umbilical cord but he says it is the penis. the ultrasound view is hard to tell. i am 21 weeks pregnant

Can repeat later: If the Ob did the ultrasound themselves, than I'd be more inclined to trust their judgement (based on their experience). You are right to question, as many times we all can be fooled. You can ask at a later ultrasound to make another attempt at identifying the sex. Please remember, we are human.... and even if we "think" we see something, it's rare that we are 100% certain!
