Severe cramping

Jessica
At 32 weeks & 6 days, I was working & I started having contractions. So I called my on call & she told me to get to labor & delivery as soon as I could so I did, and they gave me 3 pills to stop the contractions and they didn't work so then they had to give me a shot and finally it worked. I was 1cm dialted then, 5 days later they checked my dialted and I wasn't dilated. Well now I'm going on 36 weeks, and I'm having severe cramping, it wakes me up in the middle of night & everything. Does anyone know what this could mean??
