Prodromal labor?

Alissa • Dear son born 5/7/18. Three angel babies. Dear son born 8/27/20 and pregnant with our first girl and last baby Pittsburgh PA-C

I am 38 weeks today and I was up last night from 130-330 AM with mild contractions. Eventually, they stopped and I fell asleep. I went to see my OB today and he said I havent progressed any since last week other than baby has dropped a bit more.

Ugh I really thought this was it! Anyone else have something similar? How long did it last until actual labor?
