4th trip to the hospital to stop contractions

Each time is different with a positive outcome, but it is so frustrating. The best diagnosis they have for me is "irritable uterus." The recovery is more difficult each time. If I add up the hours of preterm labor, it's at 4 days. I've spent 8 nights in the hospital...it's nice to have a place to vent. This is my third child and by far the most difficult pregnancy!
