so this is the first time this has happened to me.. i’m 22, have had a few periods that were a few days off from my typical cycle (maybe 1 or 2, 3 at the most). I’m now six days passed when I was supposed to start. I took two pregnancy tests thinking this was the obvious case but they both came back negative (i’m also on BC so wasn’t expecting a pregnancy to begin with but always wanna make sure.) I’ve been eating normal, no major lifestyle changes like extreme exercise or changed BC.. does anyone know what could be going on? Is this something that has happened to others or does this mean I should make an immediate doctor appointment?
