take a test, or no?!

today my mom stopped me and said "dayum, is it me or did your boobs grow three sizes? you pregnant?" and Tbh, I didn't know just how to respond. like Yeah mom I could be but Idk. so then I'm really thinking about it. like my period lasted two days which is really really weird, it usually lasts 7-9 days.. my boobs hurt. I'm incredibly emotionally. and I can't stop myself from eating all the time. should I take a test? or is this just me overreacting..
