I am 24 weeks pregnant and woke up this morning with really bad pain in my lower left back that went to my left side of the tummy. Went to the hospital and they said I don't have a kidney infection. I have very little specs of blood in my urine they said I may have a stone and to drink lots of water and gave me pain meds. They also put me on a medication that will push the stone along and let it come out. I was in the hospital and they put me on three IV bags. I am wondering how long will this last. They said could be a few days to a few weeks. I would like some feedback of people that have had them while pregnant.
