What’s going on???

So my period was 11-12 days ago, and today I’m having like a light brown discharge when I use the bathroom and yesterday my boobs starting killing me, usually they only hurt the week before a period, but I just got off so it can’t be that and I know it’s close to my Ovulation day but could it be here early? and why is this my first time ever seeing this? I’ve been ttc for 4years and I’ve never had this so I’m kinda confused but I’m also very irregular, sometimes I’ll skip a month or two of AF, but does anyone know what this could be lol??
