16 weeks and finding out the sex

We didn't intend to find out the sex of Baby Welch today, but we couldn't help it!  We visited the Perinatologist because of some concern with blood clotting indicated by some blood work which we found that there is no reason to be concerned! 
During the sonogram the doctor mentioned that we shouldn't have another sonogram for 4 weeks since we had one today, so the thought of waiting 4 weeks until finding out the sex was too long, so we found out we are having a BOY!!!!  And a healthy (at least so far) boy!  We haven't decided 100% on a name, but Maddox is what we love the most as of now!
