34 weeks and 3 days!

I’m currently 34 weeks and 3 days. I went to l&d for contractions yesterday and I’m dilated to a 3 and I’m 20% effaced. They kept me over night and I was still have contractions the whole time I was there and I got sent home around 10:00 am this morning. I’m still having contractions. They didn’t give me anything to stop the contractions or any medicine. I have a follow up appointment next Friday. I’m still having pressure and contractions. Anyone else have this? How soon will I be going into labor? The contractions I’ve been having aren’t bad, they are mild and every 5-10 minutes. They told me to come back if it gets worse but I’m worried the pain won’t change. Advice please!
