L&D already?

I made my first dreaded trip to Labor and Delivery Wednesday evening. I started to not feel good at bowling with Jenna and it just went downhill from there. I started contracting every 5 minutes or so and knew something wasn't right. After debating for over an hour on if I should call my doctor or not, I decided to call. He said it's way too early and head over to the hospital. They started monitoring me and the contractions were coming every 1-2 minutes by then. Thinking I may be dehydrated, they started an IV but with no avail. They decided to give me a shot of Terbutaline to stop contractions. Luckily after about 20 minutes they subsided. Not to get gross but my urine culture came back with a possible infection and also blood which points to my kidney stones. I had been fighting the stone pain for a few days so I already knew that I had one. By 10:00 we were heading home with a script for my "infection" and told that if I start contracting then I need to come back. I couldn't believe this was happening. All I could think about was how tiny this little baby still is and how I couldn't imagine delivering such a little baby. Today I am feeling better and even passed another stone so hopefully that was what caused the contractions..guess we will have to see. I can only hope that this little girl stays put and I am not put on bedrest. How would i take care of my 10 month old and my 7 year old while on bedrest...oh geez.
