Still having cramps at 4w6d?

I’ve been worried the past two days because I’m still having cramps on and off.

They started last Thursday when I found out I was pregnant. I’m considered 4w6d, but I had an ultrasound 11/20 and we saw I was ovulating, so I’m tech about 2w -ish.

Is this normal? Should I be worried? I have an appointment on Friday, but this afternoon I had diarrhea which was odd. I’ve been a little firmer/inconsistent the past 10 days or so, so it was unexpected.
