Sorry for the let down, but we still don't know. Our little one just didn't feel like spreading his legs for us to get a good view of his nether regions. (I know, I know, it's probably confusing that I'm still writing "he," even though we don't know which pronoun we will be using permanently, but I'm sticking with the pronoun I chose in the beginning to make things easier. I'm not into writing "he/she" or "it" for 4 more months so until we know more, "he" it is.)
But really, the opportunity of finding out our baby's sex was the least important bit of information we could've received on Wednesday. I am so incredibly grateful for all the great news we got. During the ultrasound, the technician looked at the baby in even greater detail than she would have at a typical 20 week ultrasound. I take a medication to control epilepsy and with it comes some risk of birth defects, so they wanted to make doubly sure that everything looks ok with our baby, specifically with his heart. She didn't see any cause for alarm, and every measurement showed his growth as being right on, or even a little bit ahead of, schedule.
Still, everyday, I'm struck with how amazing it is that a baby is able to grow inside of me. What a miracle.
