Jackie • 24 y/o Jake G 💍 mama to LNG 4/21/17 👶💙. SAHM . Idgaf about your opinion. It doesn't phase me🙌I say whats on my mind. Gtfo my page if your a hater. I don't need that type of drama. Stay blessed . 🙏🏻
Today as I was using the bathroom I noticed a yellowish glob like an inch in length in the toilet. Is that part of my mucus plug or does the mucus plug come out all at once? 
Also another question I had was if the mucus plug does come out does that mean that I will go into labor soon? I am 34+4
