12 weeks pp question

First time mom here, I’m 12 weeks postpartum and I’m still excessively sweating at night. After I had my son I had it really bad where I would soak through my clothes at night but it went away. In the last 2 weeks it’s started again and I’m not sure if this is normal or if I should call the doctor. I literally wake up with my hair soaked to the back of my neck. I asked my mom and she said she thinks it’s my hormones leveling out again but I think it’s odd it went away then came back. Anyone have any similar experiences? Should I check with my doctor?
