Anyone experiencing my symptoms?

Ali
Just wondering if anyone is/has experienced my symptoms. This morning I was having really strong contractions that were 7 min apart. They lasted for 2 hours and slowly started to get further apart and turned into menstrual like cramping. Im waiting until tomorrow morning to phone my dr and get his opinion but it's now 10pm and I'm still cramping pretty bad. My low back, around the tail bone, is killing me. I've tried extra strength  Tylenol and it's not helping with the pain. I've been in L&D twice for false labor (dehydrated). I've drank 3/4 of a gallon of water so I know I'm not dehydrated. Maybe "growing pains" from baby having a growth spurt??
Should I just wait to phone my dr in the am or head to L&D?
