When should I go to L&D?

I was getting ready for bed and I had pressure and the my shorts got wet. Well this has happened before but last time was pee so I figured this time was also. 😳 Now for about an hour I've been having contractions that are painful but not unbearable. They are about 4-5 mins apart and about 45-55 seconds long. Should I wait for them to get closer or more consistent?
