Are these signs of preterm labor?!

Becca
I'm a FTM and will be 30 weeks tomorrow. I know the baby is getting pretty big but I have a consistent urge to pee and feels like something is about to pop out down there if you know what I mean. My mom asked me today if I've dropped when I walked into her house so now I'm nervous that I'm going into preterm labor. Is this normal? It's extremely uncomfortable.
