is it in my head?? help peeps

Hey do if anyone has been through this please help me figure this out? So my boyfriend got off roids last week and during sex he said I've been off it for a week then blew inside me sorry to be so straight out I'm just freaked out I'm due in 6 days for my period..symptoms I've been having the past 2 days are itchy breasts and cramping.. IS IT ALL IN MY HEAD or is it pregnancy symptoms??
