20 week ultrasound!

So my husband and I went to our 20 week ultrasound to check make sure the baby is developing correctly and to find out the gender. Baby is healthy but couldn't tell what it was. She saw what she thought was scrotum but not much of a penis if it was but it could have been swollen labia but it looked a lil more than that. So we still don't know. I'm hoping to talk my doc into doing another one at my next appointment.
