Period or Sweating?

So my apartment doesn't have AC (which is fine, it barely hits the 90's here) and so sometimes, especially if I'm cleaning, I sweat. And nothing sucks more than getting that feeling of "Crap, did I start, or am I just sweating a gross amount?" Sometimes it's great, because you catch your period starting before it can make a mess of your pants. Other times you're just grossed out because you forgot it was possible to sweat that much down there. Am I the only one this happens to? I hope not, otherwise I'll probably need to see my doctor about more than just allergy meds...
