Nope. It regenerates. I lost mine numerous time during both my pregnancies starting at about 24 weeks. As long as you aren't in pain or contracting you should be fine.
You can wait til your next appointment I'm sure. I've been losing bits of mine and having a lot of pressure and I had a doctors appointment today and told her about it so she checked me and I have already started dialating so she is checking my cervix length to see how close I actually am and I have to start going every week now but she is?kt even making me stop working this week. I'm 31w3d
What is that im 27 weeks with my first.
