Discharge and smaller bump

I am just about 28 weeks. I've been noticing a lot of wetness down there lately.. I don't think it's urine because it doesn't really have a smell (if anything it's a sweet smell). I don't know if it's sweat, discharge, or what. I've been sweating a lot lately at night, especially, but idk if this is sweat. I did wear a pad the other day just to see the color, and it felt like I had my period. Clear, not yellow.

I've also noticed that although the bump at the top is hard as a rock, the bottom of my bump is smaller and squishy feeling... Baby is sitting down there as that's mostly where I feel her move.

Should I be concerned?

Could this just be normal discharge at this point?

My biggest fear is that I'm leaking fluid.
