Wth is going on

My period went off 3 days earlier than normal and two days after that I’ve had random spotting. Idk what’s going on with my body because I’m having some random cramping too. I’m nervous because this is pretty much the same thing that happened a year ago when I found out I was pregnant with my son. I’m also scared because of I am pregnant again it’s going to suck because my boyfriend just moved out of state for work. I’m literally just hoping my body is just being weird and I’m not pregnant.
