Is anyone else suffering with a lot of hot flushes on a night?

I literally sweat really bad on a night and it's been happening for 2 nights now. But when I kick the blankets off me I'm freezing so I'm going to put the blankets back on me but then I struggle to sleep. The sweat is that bad it's soaking my pjs so then I'm having to change them, I've even tried sleeping naked but I can't seem to shift the hot flushes.. Is anyone else experiencing this?

I'm 37plus1day pregnant to :/
