Almost had a baby....

I almost had our baby last night. I have been getting really hard contractions for the past two days and decided to go in last night to get checked out. Turns out I am already dilated to 4 cm and 70% effaced. But the Doctor on call was really worried at I am only 36 weeks so he decided to stop me from going in to labor. I'm so annoyed! I could of had a baby in my arms right now! They stopped the contractions by hooking me up to an IV of something and giving me a shot of Terbutaline to stop the preterm labor. As soon as I got the shot, my body started shaking uncontrollably and I started freezing. About an hour later the contractions were really spaced apart and I was sent home. I am still kinda jittery and I have started to get contractions again today. So we will see what happens. I just don't want to have to go in again and have them stop the labor again.
