Yeah that is definitely worry some.
I would stay in bed as much as you can . you don't want to risk going into preterm labor.
When I was 17, 3/4 of my cervix was surgically removed because of precancerous cell growth. I wasn't told that I would have any complications in the future, when I planned to have children. I wasn't even told that such a drastic procedure was performed. It was only supposed to be a small piece, which I later found out could of just been frozen and scraped leaving my cervix intact. That OB no longer practices medicine. Anyway, in my first pregnancy being completely unaware of this I continued to work. I kept experiencing weird spotting and bleeding. After being examined, I was characterized as "high risk" and put on complete be dress. I had dilated 1cm by 5 months. They were going to perform a procedure called a "cerclage" which is simply putting a stitch in the cervix to keep it closed. As the baby grows, it pushes down on the cervix. Which causes premature labor and early dilation. In my cause, when I went to have the procedure done I was actively still contracting and my cervix was too short. If the stitch rips open, it can be disastrous for mom and baby. The final treatment was total be dress and progesterone injections. Along with steroids to help the baby's lungs develop quicker. Premature birth was inevitable. I also ended up getting pre-eclampsia and having an ER c-section at 29 weeks. My baby was 1lb.7oz. He'll be 18 next week. I also went on the have 4 more children, which 4 out of 5 were born prematurely because my membranes ruptured. They're all healthy. My last child was the only baby that I carried to term. So, progesterone shots, possibly a cerclage, and bedrest are highly recommended. Also, you need a perinatologist which is a high risk OB. They must monitor your cervix very closely. I hoped that helped. Good luck.
Thank you for your answer and I'm so glad that u have 4 beautiful children. I'm currently been seen by specialist once a week and my cervix is getting better, today I have appointment wish me luck. My doctor told me weeks ago she couldn't do cerclage cause I was contracting but my cervix seem longer now 4.1 last measure they took. Hoping for a good measurement today :-)
