Scared

Ok so question.. I’m 32 weeks been hurting at the bottom of my stomach for 2days. They check

Me Friday I was a 1/2of centimeter.. last night I couldn’t sleep at all I tossed n turn again my bottom part is constantly hurting. So I got up at 6 n took a shower.laid down until 8 woke up to my underwear wet.. it can’t be my water because it’s not alot a wipe n it’s a lot of discharge and I’m extremely wet on the outside but not inside. What could this be?
