Had our 20w ultrasound today. As you may remember, we've been a bit concerned about the results of our quad screen bloodwork, which showed a much higher risk of Down's (1 in 29 was the figure; 3%). We decided against getting the amnio, for various reasons (including the fact that they did the quad screen way too early--at 12w instead of the usual 16, and the general unreliability of the test), but wanted to see whether the scan showed any soft markers or other elevated risk indicators.
The happy news is that everything looked EXCELLENT--baby was measuring right on target or slightly ahead, and the heart, brain and other organs all looked fine. Heart rate was 143 and strong, and we saw baby moving around and generally being cute. Yay! So all this apparently cuts our risk in half (since half of DS babies show markers on ultrasounds), and it definitely put our minds as much at ease as possible.
We also found out that the placenta is anterior, which explains why baby's movements have felt somewhat muffled (mostly squirms, not too many kicks yet, and nothing from the outside), but it's far from the cervix, which is the most important thing! Baby was also breech, not that that means anything at this stage.
We had decided to find out the sex, and the big surprise for me is that it's a ........... BOY! The kids and I were so sure it was a girl, so I'm dealing with some gender disappointment (though nothing too serious--I think I'm almost already over it, 5 hours after the scan). ds was sooo excited to have a brother on the way; dd (who was overtired and already cranky this afternoon) cried for 10 minutes in disappointment (which was hard for me to deal with as I'm already feeling sad that she won't have a sister ), but she too seems to be over it already. I'm somewhat sad about getting rid of all our baby girl clothes and also apprehensive about having to name this boy-child (boy names are SO HARD, ugh). But I'm really glad we found out now, so that I have this time to work through my feelings!
