My period ended about a week and a half ago and now I'm getting this strange light brown discharge since I work up. It only shows up when I wipe. Also the past 4 months my periods (have also never done this til now) went back and fourth between short light bleeding for 3 or 4 days and late 2 weeks to on time and normal heavy flow for 7 days (like they usually are). One month I had 2 periods back to back and completely missed my next one took a pregnancy test it was positive and well ended up having my period so I brushed it off because I'm young and have pcos so I'm not sure if I could be pregnant or what?
