Weirdo symptoms? Or normal?

I’ve been in and out of sleep since about 3am, I seem to be having contractions, but there’s no rhyme or reason to them and I’m cramping constantly so it’s hard to tell when I’m having a BH or when I’m having a real contraction. So I haven’t really been able to track them. The cramps are kind of like period cramps but also kind of like an on set of diarrhea?

Is it something I ate or is this normal?

I’m 37w 1d and yesterday I was 50% effaced, baby had dropped, but no dilation at my docs appointment.
