Contractions have started

Mrs

This is my second baby.I’m 39 + 5 & my contractions started 10pm last night (6.5 hrs so far).They are about 12 mins apart atm & lasting 1 minute each,but are getting stronger each time.I’d nearly had my first baby by this time so not sure how long this goes on for (was hoping the second would be quicker 🤦🏼‍♀️) Can anyone share if they’ve had the same experience pls & how long it took to get to 2 contractions in 10 mins?Thank you!
