wtf happened to my nipples?!

iL
I'm 13 weeks pregnant and I thought my nipples were looking larger and darker than usual but haven't put my thought into it. 
....until my husband pointed out the change 😐
He can go weeks before he notices I changed my hair color but he picked up pretty quick on that, so now I'm worried it's really obvious. 
Did anyone else have this issue? Did they go back to normal? How big will these jokers get?! I always had dainty cute little nipples and now these monsters are freaking me out 😳
