How do I know if my baby dropped?

I’m 34 weeks today and I can’t really tell that she dropped from looking at my stomach but I’ve been carrying low. I can feel her really low I’m having a lot of pressure low in my crotch area and pelvic area and I’m having a lot of pain down there too. I also feel like I can breath better and I’ve been nauseous that past few weeks constantly feeling like I need to gag and now I’m STARVING and can’t stop eating. I am also peeing a lot more then usual.
