Is it normal?

Stacy

I’ll be 38 weeks tomorrow an for the last week or so only at night time Ive been getting really warm hot flash like, especially in the middle of the night I wake up sweating I’ve even turned the heat down I’m anemic so that’s something I never do an our room is usually cold because we live in the attic of our house. I’m just wondering is this normal I’m a first time mom so I’m just wanna make sure it’s nothing to call my doctor over
