Weird things happening to me

Okay so my period didn't come today like it was supposed to and last month I had early spotting before my period and I was ovulating and had unprotected but he pulled out, I've been having bad back aches and my whole lower abdomen is like sore it isn't bad but it hurts and I've been extremely bloated for the past like week and very moody and hungry and my favorite foods make me want to throw up because the smell.. What's going on man
