Im worried Over something stupid.

I recently Been Reading over A Bunch of things in my Health class. Im 16 years old and We got to When women Breast feed. See Ik im not pregnant bc Im Virgin and Just got my period. But when i got home and was getting changed I thought my Areolas are too big. Im a 36C cup and Very Immature. So i dont know What to Think. I cant talk to my mom because then she asks if i have been Intimate with a boy.. i Literally have mo response for her. So i’ve come here. You guys have helped me out so far and Helped me alot with My Mental state of mind too. So if anyone has any Idea of If its normal or Just Me having to Mature and they will get smaller over time please let me know. 😭 im freaking out about what my Partner might think if he sees.
