Natasha • Periods suck

My breasts are i guess you'd call it tender, idk if its because i've been wearing push up bras (-Because i have small boobs for a 14 yr old😂-) or if its just because? It kind of hurts time to time and im with my father so if there was something wrong it would be really awkward, im flying back to my moms house in 13 days though. But a few days before my period started it just got really tender and slightly hard. Help?
