I had my 26 week appointment today and am a bit worried about my cervical length. My OB has been checking it via ultrasound every 2 weeks since 16 weeks, and through 22 weeks it always measured 4cm or over (which is a great number). I started having B-H contractions at around 22-23 weeks, and at my 24 week appointment my cervix had shortened to about 3.3 cm. At today's appointment, it measured 2.9 cm.

OB says I am still in the normal range, but suggested I take it easy for the next few weeks just to be safe. I'm worried about the constant shortening - isn't it likely that when I go in for my 28 week appointment, it's going to be even shorter? I know OBs start to get concerned when you hit 2.5cm or less.

I'd be interested to hear other multiple mommies' experiences with their cervical measurements. Once yours started shortening, did it continue to do so until you gave birth? Do you ladies think I need to be nervous about being below 3cm with so many more weeks to go?

Any insight is appreciated. I'm pretty worried about this!
