False Labor

I'm a FTM and my due date is tomorrow Sept 11th. Friday night at 1 am I started having contractions and they were regular. Like 3-4 mins apart. I waited until they became stronger to pull the trigger on going to the hospital. Which was about 7 am. In the middle of the night one of my boobs started leaking which I thought was odd. I've also been steadily loosing my plug for a few days. More that night than ever before. When I made it to the hospital, my contractions were irregular and I was still only dilated to a one. 🙄.. so they sent me home. Ever since then, my contractions have been few and far between and I'm super sore after all the contractions from Friday night. Is it normal to have regular contractions and then nothing at all???
