Bladder infection

On Monday I called my Dr's office with bad back pain, they said it's normal just if it gets worse call back. Well Tuesday came around and the pain came back even stronger, instead of calling the Dr's office I went right to the hospital. I hooked up to the monitor, they asked if I was feeling any contractions ( first baby) I said I don't think so just bad pain in my back that comes and goes. They did some testing about 2 & 1/2 hours later I was discharged with a bladder infection and mild contractions. I'm 34 weeks and still haven't had my shower so I'm hoping she holds off a few more weeks!
