Is labor near?

Hi everyone, i am 38 weeks and 2 days. Since yesterday ive felt sort of "off" like a strange feeling that im not myself. All day yesterday i was crampy and having braxton hicks all day and losing bits and pieces of my mucus plug. Well today, i woke up feeling super shitty and still not "normal". Im still really crampy with braxton hicks and back pain. All last night i was up with really bad indegestion. Im really nauseas and i just went to the bathroom with diarrhea for the first time this whole pregnancy! (Tmi). Im not getting my hopes up but could these signs mean labor is near? I looked it up online and they all point to early labor symptoms but i was curious, did any of you mamas experience these symptoms before going into labor?? Thanks in advance!
