36 weeks, new symptoms

Chantelle • I'm Chantelle, I'm pregnant with my first baby, and I'm having a little girl :) I'm so excited for her to arrive!
Hi, I'm 36 w 3 days and since two nights ago, I've had some symptoms start. On the 14th I had period like pains that went from my lower timmy, through my back and down my legs, and lost some of my mucus plug. I went to sleep and when I woke felt okay for a bit until about 11 am when I felt like I was just going to vomit with a few more of those pains. They have since subsided mostly but now I have diareha! Has anyone had these symptoms? Does this mean I'm close?
