My nipples are getting darker I’m 10dpo could it be an early pregnancy sign ?

Nipples are way bigger and darker than they usually are.. I NEVER have a bra on so I know my nipples like the back of my hand and so does my fiancé. He’s the one that noticed first which made me want to take a test and I got a vvfl... I don’t want to get my hopes up but this is extremely unusual for me. I also read online that nipple darkening due to

pregnancy can Happen as early as 2 weeks in.
