go to hospital or not yet....

I've been up on and off since 1:30 this morning with contractions, it's now 10:15. My doctor had told me to go when they are 5 minutes apart, mine are not 5 minutes yet but they are pretty consistent because if I would fall asleep, they'd wake me up. Some are 8 minutes apart, some came 20 minutes apart but still consistent from 1:30. I'm a first time mom, so idk if I should go or if they will send me home...
