Pms or just being dumb

I dont know what's wrong with me. I just started crying for no reason. I don't know if it's just me, but it feels like everyone around me is just in a sour mood today! My best friend told me to shut up (jokingly, but it still made me upset.) and my allergies are acting up so my SO told me to go lay down, and that made me upset.... My boobs have been slightly tender for going on a week now. More so in my nipples. Not due for AF for another week and a half. Been cramping too...
