Dalia, I researched that stuff because I'm high risk for a shortened cervix. I have read that if you go on complete bed rest, it can grow back. I guess if it shortens anymore, they will take you off from work. I'm sorry to hear that, but I have read some success stories.
I got sort of bad news today also. My Doc called me to say that he referred me to a high risk Doctor because according to my recent anatomy scan, Twin B is 2wks behind Twin A. I'm trying to remain positive because the Doctor said there is nothing to worry about right now, yeah ok. The Doctor said that Twin A was measuring 564 grams (1lb 2oz) and Twin B was measuring 409 grams (0.9 lbs). I'm hoping that the ultrasound tech got the measurements wrong, because she was new. We will see, but having to wait two weeks to see the high risk Doctor is going to be hard as heck. I researched this and most women are placed on bed rest and told to increase their protein intake when one twin is lagging in size. So I'm going to increase my protein intake in the meantime. And I think there is a high chance that they will take me off from work once they see me in 2wks. The many things I have to worry about. Grrrr
