3 cm dilated, 60% effaced!

Went in for my 38 week appt today to find that I’m 3 cm dilated and 60% effaced. I also had high blood pressure so I was sent to labor and delivery to be monitored, but everything looked okay and I was sent home. I’m happy to be in early labor but I’m curious how long I will be in this phase. I know it’s different for everyone, but what was everyone’s experience with being sent home in early labor? How long did it take for you to get through early labor? Hoping to have baby out soon 🤞🏽
