so I started having back pressure cramping and some sharper pains in my abdominal area. it went on for an hour I finally called the doctor and they sent me to L&D; to be checked out. I was there I had plenty of fluids nothing was off with BP or anything. I was hooked up to track what contractions I was having and my baby's heart rate. I was put on Iv three hours in on monitoring and a hour and a half of the Iv the nurses come back in to tell me the contractions were getting worse instead of better so the fluids weren't helping. they call my doctor and so I got a shot to help stop or at least slow down the contractions. within a half hour they slowed significantly and the full hour they were gone and I was sent home. now im worried that he'll be early. im only 33w and 6d. this is too soom for this I need some success stories please!!
