Pain and dilating

Megan

I been on and off with my sleep due to contractions and I am 4.5cm dilating. The doctor wouldnt let me stay in the hospital due to my contraction not being enough. All my mucus plug been coming out a lot even with small bloods from him checking my cervix. I am so tired. I was in the hospital from 9am-7pm yesterday. I just want to hit 5cm already. He can feel my son head and the water bag. Has anyone ever had problems with contractions?
