How do you know when baby has dropped?

The only thing I keep reading is that if you can breath easier and eat more but I’ve never had a shortness of breath and eat loads anyway, I’m not uncomfortable in any way and haven’t been throughout my pregnancy, the only thing different from before is that when I get up from sitting it’s a little harder but that’s only ever so slightly apart from that I feel no different from being not pregnant. So how do I tell if he has dropped? Cause some days he looks lower and others he looks higher, I’m so confused 🤷‍♀️
