How long till real labor? FTM

I’m having contractions 10 minutes apart. It’s 9:20 here and my boyfriend has an interview for a job that is huge for our family @12 and I won’t let him skip it. I have time right? How long do you think I have till they reach 5 min? Also our 4 year anniversary btw, would be special if baby came today! However I know labor can last hours and hours.
