Dark nipples after surgery? 🤔

So i just had oral surgery yesterday to remove my wisdom teeth and I also noticed yesterday that my areolas appeared slightly darker, bigger and puffier than usual.

I am on the combo birth control pill and I take it every single day in the morning. My boyfriend and I pull out too.

Could it just be a side affect from surgery or medication or something?? I really really do NOT want to be pregnant.

I have no other symptoms other than tender boobs that seem to be getting better.
