i have been sweating excessively for about 2 weeks now. it only usually while i am at work. and there r times i do sweat when my office is hot but its not hot n there and i have rolling sweat. i also havent started period. Im irregular and usually go 2 weeks on period. my last cycle started june 28th & went for 2 weeks. Usually i would have started by end of July. im sure its nothing but the sweating is out of my norm.
