I'm sorry long post

Thursday night I was at work and kept feeling sharp pains in my stomach and back. I finally decided to leave work at 7p.m. and go to the hospital, turns out I was having contractions, they gave me 4 shots to stop my contractions, and gave me a shot for baby's lungs. They discharged me at 7a.m. Friday morning, and told me to come back Friday night at 11p.m. for another shot for his lungs. Friday around 2:30p.m. I started having contractions every 5-7mins, for 2 hours. I didn't go in because I knew I had to go back in that night. The contractions went away until an hour before I had to go in for my second shot. When I went in they hooked me up and found out I was having contractions every 5mins. They tried to stop them with a pill this time since the shots didn't help the night before, well my contractions only became more intense and came every 3 mins. They checked me and I had dilated to a 3. They started me on a Magnesium drip at 4a.m. this morning. They will wean me off the drip starting at 4:30 in the morning, if the contractions pick back up, they will send me to Dallas, I will be 31 weeks tomorrow, and I'm so worried 😢😢😢
