Night sweats?

I had night sweats early in my first trimester and now that I am in my third I am experiencing them again. I wake totally saturated from sweating so bad. I don't sleep with the covers on except for my legs. I also have the fan blowing on full speed. The heater is on 55 so I don't freeze my husband in the winter time. We don't live in a hot state so the climate isn't an issue. Anyone experiencing this?
