Signs labor may be coming?

Hey guys,

Last night while on a walk with my husband, I noticed I felt like I was “leaking” a little so I went to the bathroom, and sure enough there was just a little bit of water like leakage (pretty small amount) and some mucous like discharge. I also had a few bigger “pieces” I guess you can call it, of mucous come out yesterday and felt a little light leaking again this morning. Now I’m a first time mom but I strive to not over think anything and just try to remain calm. But I was just wondering if it seems like these little things could be adding up to the big day? I’m 37+4. Thanks in advance. 😊

I should also add, no contractions yet.
