Mucus Plug

Brittany • Hello everyone! I am 24 and pregnant with my first baby, my boyfriend and I have now been together for almost 4 years!
I'm 29 weeks and today I have went to the bathroom several times with thick white and yellowish stuff on the toilet paper. One of the times I looked in the toilet and there was some darker stuff down there too. I'm not sure if I'm losing mine or not..
