Nearly 2 years ago I had a Leep procedure done due to some bad cells. I am currently in my 16th week of pregnancy. Yesterday for precautionary they did a transvaginal sono to measure the length of my cervix. The measurement came back at 3.7. My doctor said that is not measurement they are concerned with but they will check at 20 weeks just to be safe. I wasn't too concerned except for the fact I had Google cervix length and 3.7 seems short! Ugh I don't want to stress over something for the next 4 weeks. Any similar experiences?
