So unsure if I’m pregnant or not

Britany

Okay so I was supposed to have my period on January 2nd it is not January 6th and I still do not have my period. I took a test on January 4th and got a negative....but I still don’t have my period. Yesterday I did have some cramping, so I thought it was my period but idk. Last month my period came a week early....I need some advice on what to do....
