Im aggravated beyond normal aggravation

I will start out by saying that Church last night was very good.
Afterwards we went to eat and after I had eaten, I started contracting all the sudden every five mins. They were really bad ones too. I drive myself home and get ready for bed and lay down and they start slowing down. Eventually stopping. (once again) About an hour an a half later they start up again and this went on all night long. I was up most of the night. By this morning I was so exhausted and just plain done in. My belly was sore from so many contractions. I called the doctor office to see who was in today. Come to find out, no doc in till this afternoon. B/c of the night I had, the nurse said for me to go to hospital to be checked. I told her no I didn't want to b/c I didn't want to be sent home again. She said she really thought I should be checked and that she didn't think they would send me home this time. So what do I do? I get ready to go, drive myself to hospital. While having contractions, but not as bad as the ones I had all night. I check into the birth center, tell them what I had been told to come in for. And what do you know, when I get checked, I'm not about 4 cent any longer. I'm 4-5 now. My contractions were not consistant, and you guessed it. They just sent me home. Oh my goodness, I'm like beyond knowing what to do. The doc flat out told me that my labor would prob happen like hers. I would be 8 cent by the time I get to hosp, get in the room and get my IV and then 30 mins later end up having a baby. Just so you know, she didn't mention getting an epidural. I want one. But it sounded like I wouldn't have time for one.
So my question is, how many cents do I have to be before they decide to induce me, if my contractions aren't consitant? Or how can I make my contractions stay instead of quitting all of the sudden. I need help! I need to have this baby. I have decided that this is my last pregnancy. One boy and one girl. Even though it's after 2 in the afternoon, I'm going to lay down for a nap b/c I need to get some sleep. After Ray gets off work, he will be getting Logan, and I want to rest up some . I'm glad he will be coming home though. I have really missed him, and it broke my heart last night when he cried b/c he wanted to come home to me. It will be over soon and I will have my little man and my little lady.
