I have weird nipple questions

10 days on birth control and I noticed that... okay well you know how when you’re warm your nipples/areolas get puffy and if you’re cold they get hard? When I get warm only half my areolas get puffy.

So I’ll look down and my nips look dumb sticking out sideways and It’s honestly kind of freaking me out? I mean I’ve never looked down and saw that I have half puffy and half erect nipples and it’s the weirdest looking thing ever. I know that it has to do with being warm and cold because if I touch them they perk up and look normal again. Is that normal or should I worry?
