29 weeks. Has baby dropped?

La

I’m 29 + 4, been noticing odd feeling down there , like burning sensation but only when standing and walking. Also feeling need to urinate when standing or walking ( haven’t had that till now in the pregnancy). Haven’t had this before! Been reading about baby dropping , is this likely this early on? And how do you even know if that’s happened? Or is it just pressure from the baby? I doubt its UTI as there’s no burning when I go toilet or other times.

Anyone experience this? Obviously I’ll need to talk to my midwife but quite worried now! It’s my first. X
