Wanting some experiences

I went to the hospital on Monday because I thought my water had broke and found out it wasn't my water but I was in labor with steady contractions so they gave me a shot to stop the labor. On that day I was dailated 1/2 cm and 0% effaced. Today at my appointment it was 1cm and 25% effaced. So my question is has anyone else dailated that quickly and what everyone's experiences with how quickly labor started afterwords? This is my 3rd baby but my others were so much different as I I went to the doctor for an appointment was 6cm and was sent to the hospital. Just want some ladies who can help ease my mind a little I guess. Thanks.
