Second pregnancy pressure?

Jené • 23 years old married, mommy to a beautiful daughter 12-22-13 and handsome son 9-8-15.💜💙
Im either 31 weeks or 33 weeks because I have two due dates my original one of August 24th from last period, and September 6th because he measured smaller at my 22 week ultrasound. This is my second pregnancy and I have so much pressure down there I always feel the need to pee an I even thought my water was breaking because my underwear felt wet from a constant leak.. That turned out to be urine but is it still normal to have this my pressure down there? I didn't have it to much with my daughter, my ob appointment is tomorrow and I'm gonna ask just figured I'd see if it's happened to others before. Didn't know if it was normal or if I may be expecting my little man sooner.
