Am I starting to go into early labor..?

Cassie

I woke up yesterday morning and bloody kinda dark brown mucus was on the toilet paper when I wiped.. I’m 35 weeks today. I think that could have been my mucus plug because it happened before like that a few weeks ago, but a lot came out yesterday and I had to wipe twice to get it all off. I’ve been having period cramps but it is in my lower back and I’ve also been having pelvic pressure..? Any thoughts??
