Feeling anxious/labor signs

I’m 37 + 4 and have been having braxton hicks/period cramping today since 5am that haven’t gone away. I also started to get diarrhea cramping around 10am which is new for me and went #2 twice but now I do not have to go #2 and still have the cramping feeling/pressure in my bum. All of it gets worse after I pee (more painful) but then it seems to calm down (pretty uncomfortable but not painful) but it hasn’t stopped at all. I have been drinking a crap ton of water today in case it’s from dehydration so I don’t think it is, but I am just feeling confused and not sure if I should take these symptoms seriously because I keep reading about ladies thinking they were in early labor but ended up not being in labor at all and I don’t want to get my family’s hopes up that baby might be coming if hes not. What should I do? It’s hard for me to time anything because it seems so constant.
