33 weeks labor Stopped

So I went into preterm labor on Sunday 1 Pm and when I got to the hospital , they were saying that the baby was huge for his age , but didn't have his lungs developed the whole way. The doctors decided to put me on me fine to stop the terrible contractions and preterm labor. They gave me a shot on the butt to mature the baby's lungs , they gave me magnesium (I regret accepting) it completely put my baby to sleep for 3 days, and morphine for pain. Morphine only lasted 3 hours and I woke up in deep deep deep pain. I couldn't go to the bathroom on my own. The next day still at the hospital , they decided to take me to get ultrasounds done and because of so much medicine my body started acting up. I had the chills, headaches, I was vomiting , nauseas , terrible dizziness , it was just terrible. They accomplished to stop my labor . Gave me another maturing lung shot on the butt. I got sent back home, but I've been in so much pain as if I were having contractions . The doctor said I had to suck it up & im currently 34 weeks now on bed rest!
