Side effect time table?

GlendaG • Started TTCing for #1 in Nov 2013 Married June 2014 stopped TTCing Dec 2015 now just living
So getting ready to start my first cycle do the side effect normally only last the few days you are taking the drug or the whole month? I understand hot flashes and mood swings are the most common so just wondering how long I should expect to maybe have them.
