Pelvic pressure

I'm 30 weeks and had an appt with my ob today. (Glucose test also) after I got home I've been feeling a ton of pressure and baby moving way down in my pelvis... Like feels as though he's just going to fall out. Lol. And I have to pee every hour. I've been reading that this is fairly normal and they can drop as early as this but my 1st son didn't drop until 37 weeks. Anyone else having this or have any more info on it?
