Shelly, I wouldn't worry about your cervical length. My OB told me they don't worry unless it's 2.7 or less. I am having mine measured weekly due to a low lying placenta.
I think your babies' weights look great! They appear to be in the range I see on most websites. I was seeing sites saying 1.25 to 1.5 pounds.
I go this Friday for another measurement of the babies , which will be at 22 weeks and 1 day. I will let you know what they say. At 19 weeks they were 9. 10 and 11oz. If my belly is any indication they have grown a lot since then...
Hope your bedrest is going well. I will be joining you after one more week of work. Didn't quite make it to 23 weeks but it's getting to be a bit too uncomfortable. It's a long trek to the restroom from my desk and I get pretty out of breath sometimes. Will have made it 22 weeks though. I have a sit down job so that made it easier.
How often do you see your perinatologist? I currently see mine every 3 weeks and the OB every week in between (because of the cervical measurements). The peri may want to see me more often after the visit this Friday, we'll see. Just curious how it was working for everyone else.
