Help, I get too many pimples before my period?

My skin is usually acne free, I might get one or two pimples but that's it. But right before my period I get a bunch of tiny pustules on my cheeks and it makes me so sad because I have to clear up my skin after every period I get and I'm tired of this, makes me feel so ugly. Any tips? I don't want to go to the dermatologist since this isn't a big issue, I'm just asking for tips, food or over the counter products that might help.
