35 weeks hot and sweating!

Hi, I'm 35.3 today. Starting from last night, I was unable to sleep cause I'm sweat a lot to the point where I used wet towel to cover my body. That help me sleep a bit. I feel like my body is burning. Even this morning in the office with air conditioner, I'm sweating. Tho the aircond didn't directly point to me but before this, I never sweat and feel hot like today. Is there anyone going through this? I drink a lot of cold water cause I'm afraid of dehydration
