Had contractions all night and then they randomly stopped when I went to sleep?!

So I was having regular contractions from 5pm-10pm, they were averaging 3 minutes apart lasting 40secs-1min. At around 10pm I decided to go to sleep because I wanted to labor at home for as long as possible. When sleeping I could feel a bit of cramping but nothing that woke me up. Anyways, the regular contractions completely stopped!

Woke up this morning and have had a few irregular contractions. Only just going to start timing them now.

I know they’re deffinitely not Braxton hicks because it’s not JUST tightening in the front of stomach. It feels like bad period cramps mixed with tightenings and they were regular.

I’m 40 weeks and This is my second baby too.

Has this happened to anyone? Am I just going to have this for the new few days/weeks ??!!
