You can loose your mucus plug for months an it'll grow back I started loosing stuff like that around 30 weeks an my water didn't break until 39 weeks an 3 days , mucus doesn't really matter unless it's all bloody, your bloody show . So I wouldn't be concerned momma! @momma.of.2

I can't be in full active labor

I'm already almost 2cm tho and I'm having c section so

Looks like mucus. it is common to lose it early and it will grow back again.
