my periods was delay two month today came light brown discharge what's it's reason

A. Mam since your period I have been delayed didn’t you take a pregnancy test or so because that is the first thing to confirm whether you’re pregnant or not and if you haven’t resumed your period in last two months you just get a brown discharge maybe your period has started now also we do not know whether you have a issue of PCOD or PCOS or anything of that matter so better to consult your gynaecologist once
