You have to be dilated to a 10 in order to be in labor.
Right now, you are in the early stages of labor(which you will be in until you are dilated 4 cm)
When you're contractions start getting more intense, and perhaps a bit closer together, you should head to the hospital.
But there is no certain time span in order to the 'before I go into labor' if this is you're first baby, you may be in labor for about 10 hours, but it should not be more than that.
But, like I said, you are technically already in labor, just not enough to deliver.
