30-36yrs old sweating pre-period/ keeping Weight off

I tend to sweat allot after I shower, while I'm getting ready.  It's super annoying and uncomfortable.  
​I am about 30lbs overweight at the moment. But I think I'm also about to start.  I just started using this app/log.   
​Any 30-36 year old women out there have problems with either sweating before their period, and or keeping weight off and they only started having to work at it after 30? 
​Hellllp!! ??
