Mucus plug at 29 weeks?!

Selina • ♡ Wife to My Superman♡ Mother of 4 babies ♡ Lost My Dad 02.04.19 💐 ♡ 3 babies in heaven.

I have been losing my mucus plug for a good while now in chunks! Tmi but it's like literal snot, like if someone blew a huge snot rocket into the toilet paper but it came from my vagina! I've been having BH and a lot of discomfort but so far at each appointment my cervix is still long and closed but it is really soft. I've seen it happen after sex but i don't let my hubs dump his load inside since i always get cramps from it! Every time i lose more chunks i get crampy. There is no bloody show just snot like discharge. Am i still in the clear? Should i call my ob in the morning? I'll be 30 weeks on Thursday. Also i noticed it comes more when i TRY to go #2 since the constipation has been really gnarly. Advice would be great! Thanks in advance loves! Also this is baby #4
