2 months late and pcos

hi everyone I have pcos and my cycle usually irregular but regular enough where I can track. I usually skip a month and then have my cycle the next month. my lmp was Dec. 18 and I have skip Jan. and Feb. I took a dollar store cheapie and negative. right after I noticed brown discharge after wiping which I thought was my cycle starting but nothing. I'm just puzzled and IDK what to do. I'm so upset that pcos has taken over me but I won't let it win. I also seem to always get evaps or ghost lines on test not sure if it's the pcos triggers or what
