Smell from down there?

This is extremely embarrassing so I’m going to stay anonymous! I’m in my 3rd trimester and I’ve noticed a smell from down there😳 It’s not my actual private but that area between my private and my leg. I keep finding sweat there which I’ve never experienced before and it has a smell to it. It only smelled when I touched it and smelled it to see what it was but is that normal? Anything to help it? Thx in advance!!
