Sweating on Cycle

Anyone find that they sweat more while on cycle? Specifically, armpits during the day and allover at night? I am at the point now where I have to use Certain Dri deodorant(it reduces the size of sweat glands) in lieu of regular deodorant. I do allot of public speaking so you can imagine the dilemna. Last night I actually had to use folded up napkins in the armpit of my t-shirt to combat the whole "never let them see you sweat" Any input on how to help this is appreciated. I think I may get checked for hyperhydrosis since I experience this off cycle, it is just not as extreme.
