So I've been lurking in the DDC's that are ahead of mine since there are quite a few ladies having twins. I am seeing that a lot of them start having the length of their cervix checked at a certain point. I don't ever remember this with my other pregnancies (this is my first multiple pregnancy). Is this something that is routine in twin pregnancies? Is it done with u/s? Just curious if I should expect this and if so, when...
Hmmm ... good question. I remember the MFM checking it at the two appts I had with them at 18 weeks and 22 weeks. After that I was just back with my regular OB. If they checked it then, I don't remember it.

I had mine checked because of contractions and we found that it was shortening. I don't know if it's routine, but I'd request to have it checked periodically because you never know what it's doing without checking. If you know it's shortening, then you can take it easier and hopefully get it to lengthen again. Mine lengthened back out by stopping working out, working from home instead of the office and basically doing a lot of sitting and being inactive.
Thank you peimum for my siggie

I never had my cervical length checked during my singleton pregnancy...it isn't something they worry about unless you have had previous complications.
For twin pregnancies, they usually start checking it around 16-18 weeks, and it is checked via vaginal ultrasound with an empty bladder. If it is found to be shortening, there are steps to take that can help. In the worst cases, a cerclage can be used to sew the cervix shut. You can also reduce activity, take progesterone supplements, and/or use a pessary to help relieve pressure on the cervix.
A shortened cervix doesn't necessarily mean that you will deliver pre-term, but it is does indicate that you are more at risk. Hope that helps!
I had my first cervical length check at my anatomy scan around 19 weeks. They used a vag u/s probe & got a baseline length.
My cervix started showing signs of changing at a physical exam in March around 23/24 weeks, so my doctor ordered another cervix length check at my next high def u/s. It is routine for twin mamas here to have high def u/s every 4-6 weeks from 20 weeks on to check on growth, babies size differential, and it identify any other problems. The high def ones are when they measure cervix length either transvaginally with a regular u/s wand or vaginally with vag probe. They haven't used a vaginal probe to measure this since my 30 week PTL hospitalization.
Hope this helps. I'll get a new length on Monday and I know I'm 50% effaced, but this doesn't mean much.
This is routine in any pregnancy. I only know this because I have a short cervix. Now, because of mine is short it was checked every other week with the twins starting at 20 weeks. With my oldest, it was checked when I went into preterm labour at 23 weeks.
My cervix is naturally short (2cm vs 4cm). I am glad to report that I kept my oldest in until 2 days before her due date, and was induced with the twins at 37 weeks due to cholestasis.
