Contractions started

K
I had bloody show yesterday with some occasional  pains that felt like menstrual cramps. Today these pains are getting worse and worse and so I'm calling these contractions now. The whole day they've been 10-30 minutes apart. 
My question is how long has it taken everyone to get to consistent contractions every five minutes? I know everyone is different but I'm just wondering what it's been like for others. Besides wanting to meet my son already, I'm so desperate to get some pain medication for this.
