Pain on my left pelvic area but I’m not ovulating or pregnant.

I have an irregular cycle (every 32-35 days). My last MC ended 5/15/18. According to the app I was ovulating last week of May. My period is 6 days past due. I have been feeling cramping on my left side only near my pelvic area. I took a pregnancy test yesterday and received a negative result. I took an ovulation test and it look like a negative but I see a faint line. Is there anyway I’m due to ovulate again when I haven’t had a period this month? I’m so confused why I have cramping and no period (P.S ovulation kit pictured).
