It's the "cork" that seals your cervix up. You can lose it early on in pregnancy, it regenerates itself.

@foehunnet, Girl for real lol I was just trying to give you a visual

ewwwwwww. @mommyagain

It plugs up your cervix until birth when you lose it or it starts coming out it looks like thick snot

no lol @babykeiyanna i just see alot of people talking about it.

Have you lost yours ?

No you can have sex while pregnant . It just keeps bacteria out and you will lose it when it gets really close to labor

thats y u cant have sex? @babykeiyanna

It's a long thick slimy mucus stran that's in your cervix to keep all bacteria out of you but when your about to have your water broke you will lose it .
