My first baby I had no contractions until my water broke (2 weeks after I lost my plug). She came at 32 weeks. With my twins I was in labor (contractions with dialation) at 23 weeks. I was put on bedrest and in the hospital. I lost my plug in pieces (after the dialation started) and I was also placed on a Magnesium Sulfate drip. I had a placental abruption at 26 weeks and my water was broken by the dr as I was in the delivery room. Trust your instincts. If you think you are in labor go to labor and delivery. It sounds like you could possibly in preterm labor and if you ignore it, it can be a horrible result. No one knows your body like you do. If it doesn't feel right head in there. Best case scenario you get sent home. But just in case something happens, there are people who know what to do. I had my oldest in 2 hours from the time my water broke until she came out. If I had been at home and ignored it she would have died.
