Late period, sore boobs & bc pills

Hey, so I am late again (this happens almost every cycle) so I'm going on birth control pills since I'm now seeing someone who's a man (my first sexual relationship with a man) I only dated women. Sleeping with a man + late period = freak out wondering if I'm pregnant (not a fun time wondering) ...anyways not the point. So my boobs get so tender when I'm about to start my period ....does this happen to anyone else? I'm hoping the pill helps with the cramps in my stomach but does anyone know if there is a chance it will help with the tender breast? I can't even wear my bra at the moment...they hurt so bad ! Gosh we women have to deal with so much pain 😟
