I've had night sweats off and on for about 10 years. I have had 3 kids during that time and they always went away during pregnancy returning within days to weeks after delivery. I've always assumed they had something to do with hormones. I'm 36 years old & preggo with my 5th baby, this time they did not go away, I've been having them every night & I'm currently 13 weeks. What do yall think?
