I'm around 11 weeks pregnant and for weeks now I've been waking up at around 2-3 in the morning dripping in sweat to the point where my pj top is soaked. We had recently changed to a better quality duvet and I thought it might have just been this but we changed back to a thinner one and it's no different. Last night we had the windows open and my husband was freezing but it still happened but by the morning I was fairly chilly. Anybody experiencing the same or knows why this is happening?
