Need to have stronger contractions !

Okay back story . At 9 pm last night I started having contractions . I waited 3 hours and for them to be 4 minutes apart to go into labor and delivery .  Was there for one hour and my contractions got to 2 minutes apart . I went from 50 percent effaced to 70 percent effaced and they ended up sending me home and told me I wasn't progressing fast enough . To come back when my contractions were hurting bad enough I couldn't breathe thru them .  Now I have went to sleep and woke up and I am still having contractions just not strong ones .  How can I get them to come on stronger ? I would love to actually be in labor and have my baby today or tomorrow . I will be 39 weeks on monday
