Maybe it's time or baby playing tricks on me?

I woke up today with what felt like contractions. Pain started in pelvis first then in my back, eight minutes later pain started in my back then in my back. Happened three times and now nothing. I already have my bag and baby's bag packed but not sure if I should go to the hospital. With my firstborn everything happened all at once from the pain, to the mucus plug, bloody show and water breaking all within 10 minutes but now I'm just not sure...
