HELP!

Khimirah

So I’ve been having hot & cold flashes for the past week or 2. I’ve been really trying to pay attention to see if its anything to do with activities I’m doing (at work/home) but so far that’s not it. AF isn’t due for another week/week & a half. It doesnt say anything about body temp or hot flashes when I’ve looked up prenatal vitamin side effects. Has anyone else experienced this?
