Pms or pregnant????? HEELP?

Well, I'm 14, and my period is about 2 months late, about 2,5 months ago I hocked up with this guy. So lately I've been getting like..bloated? and I've been geting the most weirdest food cravings like icecream with cereal etc. My back has been hurting and I haven't even taken a pregnancy test yet, what should I tell my parents, please help!!
