Baby might come early

Alexia

Hi mommas ! I’m 31 weeks pregnant, I’ve been losing my mucus plug for a few weeks now today I woke up after I went pee when I wiped I noticed more of my mucus plug this time it had a little bit of blood in it. I called my ob waiting for her to call me back. I’m not sure if this stuff is normal at 31 weeks but I’m nervous my baby is gonna come. I have a low lying placenta so my chance of a c-section is also higher. I had some real contractions a few days ago but they stopped, other than that I’ve just been having Braxton hicks. I just have this weird feeling I can’t shake that he’s gonna come like any day now. Any nicu mommies/daddies share ur experience, and any nicu mommies how did u know u were early labor.
