kidney stones

Sorry for the long post just needed to talk about what happened. I am 26 weeks today with my little boy and last week sucked. So I woke up from a pain in my stomach that was bad for about 15-30 seconds and then let up for 10 seconds and come right back. It got worse and worse and I called a doctor a half hour later who said I need to come in. Found out my uterus was irritable, they had to give me a shot that stopped the contractions which worked they did many tests to see what was causing it but nice they saw I was okay let me go home and said they would call me with the results. That night I started having an immense pain in my lower left side of my back and it was the worst thing I have ever felt. My fiancé brought me back to the hospital where I waited in the er for half an hour on the ground puking waiting for someone to help. Finally they came and I winded up yelling at some nurses cause they said I was gonna lose the baby cause I was only 21 weeks I was like no I'm 25 and I'm not losing anything. Finally I was brought up to labor and delivery, they waited to see if I was having contractions or was dialated or if my son was at all in distress which all answers were no. During this wait I puked again and peed myself because of the pain they then said I was passing a kidney stone and gave me medicine that helped the pain and knocked me out which I needed every 3 hours for the next day. Finally the pain stopped and I was able to come back home. They told me the kidney stone was what caused my irritable uterus and that since I now have passed it I should be fine. Another nurse said the pain is worse than labor...I sure hope that's true haha :) but I am better just sore at home and get to know my son is okay :)
