Should I start preparing?

I am 32 weeks and I have dropped quite a bit, i’m in a lot of pain and been having contractions and i’m very sore in my pelvis area. I was told she will very likely come early but I assumed 37-38 weeks. For the last 2 days now I have been having the worst poops of my life. Diarrhea terribly and been in pain and been feeling so sick to get it out and I heard diarrhea is a sign of labor around the corner or whatever “your body emptying to prepare” but how long could that last? Weeks? I’ve had loose poops for a few weeks now but now its like terrible. Painful diarrhea and a lot of it.. I know thats gross but like seriously I haven’t even bought a car seat yet.. Probably time huh? I hate this!!!
