Holy sweat!

Hey Ladies, I am just curious if this is normal. This is my first. I am 22 weeks tomorrow. I have been experiencing major sweaty episodes at night when I am sleeping. I am sweating enough that I am waking up in a puddle of water and it seems to be under my bump down to my knees. Mostly between my legs lol. Is this normal? Is it hormones? I am fine the rest of the day this only happens at night when I am sleeping.
