We went for an ultrasound yesterday just to check on everything. The baby looks great... he was super cute, waving his hands around and opening and closing his mouth until he found his thumb and started sucking on it :) His heart rate was fine, and he has been as active as ever.
Unfortunately, the ultrasound showed that my cervix (the thing that keeps the baby inside, basically) was too short compared to what it's supposed to be - it's 19mm and it's supposed to be closer to 30mm. This means that the contractions I've been having have shortened it, and caused me to dilate 1/2cm and efface 50%. Because of all that I have to definitely stay on strict bedrest to prevent any more shortening/dilating/effacing. I'll find out what the next step of the pregnancy is going to look like at my appointment on the 22nd.
So bedrest is kind of a bummer, but I'll do anything for baby boy... and I'm finding things to keep me busy!
