Mucus plug? Labor?

I’m 37 weeks today and yesterday I went to the restroom and was pretty sure I lost my mucus plug. It was egg white consistency but more of a brown color rather than more red. I had my cervix checked on Friday and was 1cm dilated and spotted slightly after but not much and then the following day this happened. I’ve been having what I think are just slightly more intense Braxton hicks (I’m not feeling any contractions I’m my back, really just my stomach and it getting tight) and horrible lightning crotch and more brownish discharge as well so I’m wondering if labor is just getting closer and closer!
