Are hot flashes during the day a normal postpartum thing??

And if so, how long is this supposed to last? 😩 I am CONSTANTLY hot and/or sweating, and it takes forever for me to cool down. I feel like a crazy person! I could stand outside and be totally comfortable in my tanktop and yoga pants. (It's 52 degrees here) my husband thinks I'm a whack job. What can I do to feel normal? 😭
