Dark Spots inside of egg On day 19

[FlexG279]

Anyone know what these two dark spots are inside of my egg, I Have 3 and this is the only one with them. My Apologies if it’s normal, this is my first time incubating eggs ever and I couldn’t find anything online about this. Thank you. EDIT: it kinda looks like they moved together idk

Hopefully the incubation/hatch is progressing normally. I see no problems with the eggs pictured. Good luck.
