Preg symptoms or crazy?

I’m 6days piui and yesterday had twinges and stabbing pain but went away .. today I feel like I’m freezing and it’s 100 deg outside. Usually I get cold feet and chills 2 days before period.. but I’m not due for 8 more days. My feet are freezing and I don’t have any thyroid or health issues. I’m wondering if this can be a symptom.. “cold feet” or anyone preg experiences this?
