Weird chills

Last night while I was dead asleep and covered with a million blankets I woke up with severe chills. Like my body was shaking a little and my teeth chattering.

It felt the same like when I went through contractions and then a c-section. It wasn’t a seizure, just shivers. It happened once before when I was pregnant with my son.

I read it can be caused by hormones or blood pressure? Anyone have this happen to them? I am definitely going to talk to my doctor about it when I see them again.

I am 10w 4d.
