Hello Ladies. I have a question to ask you: so the doctor is suspecting that I have a condition called cervical incompetence, but he will keep an eye to my cervix to see if there any signs of its dilating early. He told me there are stages of cervix that they can watch for before it open completely. He told me its range from T, Y, V, and finally U, with T and Y the cervix being really closed. My question is, has any of you gone through this issue and was the cerclage the best option or pregestrone supplement? Also, how long or what's the duration for one letter to the other for the cervix to open? i.e from the Y letter to V letter does it takes days, or how many weeks to be that letter.
