Is it the big day?

I’m 38 weeks pregnant. I’ve been having contractions since 11:30pm but they have been inconsistent and mildly uncomfortable. My last contractions were 5 mins apart then 3 then 7 then 5 then 3 then 5 then 3 then 3 then 3. My question is do I still have time to sleep or should I stay awake and head to the hospital? I’m already ready to go I just really feel I may benefit from a little sleep. Plus the contractions aren’t unbearable yet.... it’s just tightening and loosening.
