Baby dropping?

I'm thinking my baby dropped today. He certainly feels lower, and the pressure in my pelvis and on my lower back has increased. I think I maybe even had some super light contractions - they started in my back and radiated around to my lower abdomen. Made me feel a tiny bit nauseous. All of this is so weird and foreign because I've never experienced it before. What does it all mean?! Hoping I'm close to being done!
