Should I be freaking out?

So I’m 33 weeks pregnant... my son has been measuring 2 weeks ahead for about ten weeks now... (they’ve done multiple ultrasounds to confirm this)

Anyway.

I’ve been like leaking all day. Like I pee my pants a little for no reason?? But I don’t feel like I’m peeing. And I’ve been having cramps.. they like wrap around my lower back and abdomen but then go away...

Should I be going to the hospital? Could I be in labor?
