Hi Ich and sorry I didn't get here sooner
As you already said, 2cms is on the short side at 11wks, BUT from your post I'm assuming it was a nurse who did the scan and it was transabdominal? In which case her estimated cl is likely to be inaccurate anyway. The only way to get a reasonabley accurate cl is with a tvu, abdominal scans can see that a cervix is closed at the top, and give a rough idea if it is long or short, but very difficult to get an exact measurement. For that reason, I wouldn't get too hung up on the 2cms - your cervix is likely below avearge length, but not necessarily that short honey.
Secondly, resting after stitch placement is imperative in my opinion. Even if you weren't to take complete rest for the remainder of the pregnancy, you should be looking to take atleast one week off maybe two. After that you should minimise physical activity, stay off your feet when not working and give your cervix, stitch and body a helping hand until you reach 28/30wks.
There are very few clinicians who officially order rest after cerclage, and I cannot fathom why. Theoretically the stitch should be enough, and of course to a surgeon it most definitely is, but in reality I do wonder at how many women would have made it with the stitch alone but without atleast some rest as and when they can. I certainly wasn't brave enough to manage without rest, but then I had lots of pressure, aches and pains which made me too scared to do any other.
Sex and orgasms are ideally best avoided if poss, tho we have all had involuntary o's which have never been known to cause ptl and/or cervical shortening. Orgasms do cause temporary uterine contractions, but it's doubtful they are strong enough to cause any significant effects, especially when your body and that of your baby is weeks away from labour 'readiness'. That said, we took the view that anything unnecessary and even slightly risky was best avoided for what amounts to a few months.
There are so many unknowns in pregnancy, especially in ladies with a prior history of complications, so if you can Ich I would play things ultra safe and pull out all the stops this time sweet. There are so many things you can't control in pregnancy hun, but many more that you can. It's those steps that you definitely should take to help things along, no matter what the medical advice says
