chills and pms!?

Hi everyone! Lately I’ve been getting chills right before my period and it’s so bad to the point I’m under layers of blankets. I have no other symptoms that could indicate a cold (although I do feel so shitty right before my period cause I get very bad periods) I went to the doctor to draw blood and everything was completely fine. So I just wanna know if anyone else gets chills during pms or on their period as well. Thanks! :)
