Great news from our ultrasound yesterday, which totally warrants a second post this weekend: not only is my cervix still holding strong, but it’s actually grown longer, which is amazing news.
In case you don’t live and die on cervical measurements or really know anything about the cervix (I certainly didn’t until 10 months ago), basically it works like this: when you’re not pregnant, your cervix is normally long and a little bit open. Once you become pregnant, that sucker is supposed to seal up tight like Fort Knox, but it is also supposed to stay long until some time between 24 and 28 weeks of pregnancy, when it (slowly) begins the process of preparing for birth, which involves shortening and opening way, way up. So, in conclusion, unless you are nearing full term, “short” and/or “open” is BAD, and “long” and “closed” is GOOD. The longer, the better.
So every time they check your cervix, this is a margin of error. It’s an ultrasound, not a ruler, and different techs measure in different spots. Up until 24 weeks, you want a length of between 3.5 and 4.5 cm. Mine has been measuring well at an average of 3.75 cm since my cerclage surgery at 14 weeks, across different techs, different machines, at different times. We’ve all been very happy with that. Yesterday, when I went in, mine was measuring a whopping 4.45 cm. Even accounting for margins of error, that’s at least .5 cm longer than it was last week, which is kind of a big deal. It means the progesterone shots they’re giving me are doing their job, and it means the odds of our getting to or near term are going way, way up, and that? That made us so happy that this morning we did this:
Next stop, 23 weeks.
