WEIRD DISCHARGE!

So there’s quite a story to this one, at the beginning on January I was going on holiday around the time my period was due and so I took the pill and that didn’t fucking work so I had my period on holiday but it stopped mid way so I kept taking them anyway so I didn’t have withdrawal bleeding and after I stopped taking them I got my period which was around the 13th and on a normal period I’m meant to get it right about now but I’m getting brown discharge? I’m not sure if it’s period blood but the consistency is discharge! Plz help I’m worried and sorry if I didn’t explain well
