It can affect us all in different ways. Myself? I get my cycle regularly - still monthly, but, sometimes it's heavy and only lasts a couple days, other times it's very light and lasts about 5 days, and the duration is still shorter. I get night sweats, and I'm running constantly hot, but don't get the chills. I'm less patient than usual.
Other people will have out right hot flashes, followed by chills, and irregular timing of their cycles. You may get isolated areas of warm, rather than full body hot flashes. Best thing is to talk to your doctor. (S)He may be able to get you a hormone test to see if you're really going through it or not, and maybe prescribe something to make it easier if you're in need of it.
