I'm so scared 😫

I'm currently feeling like a pile of poo. 😔 I am 35 weeks and I went to sleep tonight and within 20-30 minutes I woke up due to my stomach cramping realllyyy bad so I got up and tried to poop and nothing happened. I felt my little man moving and my stomach was just extremely tight and cramping like I needed to poop but I couldn't go. So I decided to take a hot shower to see if it eased up at all. The shower didn't really help, the water felt amazing but my stomach was still cramping and I was so tired of standing there so I got out and now I am laying on my heating pad and wondering what's going on. Is this Braxton hicks? Or true labor? I was induced with my first at 40+3 so I never experienced what going into labor felt like, and I don't really remember ever having Braxton hicks either so I'm clueless pretty much. I am so terrified of going into labor and not knowing it, or it be false labor and a wasted trip to my hospital which is an hour away. It's lessened up some now, which makes me believe it isn't true labor. But could you guys give me some labor signs that happened with y'all?? Also, i don't know whether I have vaginal discharge, losing my mucus plug or my water breaking slowly? My panties have been really wet off and on for the past day or so. Help?!
