PCOS is it normal???

Is it normal for a woman with pcos to go 84 days late. I have PCOS I haven’t had a period in months. I’m not pregnant. Had X-rays done and also pregnancy test done the same day. I was in a car wreck On June 1st this year. Wasn’t pregnant and no period for 3 months at that point. I also forgot the month when filling out stuff for this app. Me and my partner are very active. I can’t be on the pill cause it gave me DVT in my right leg and PE in both lungs. This month can’t afford condoms though.
