Late periods

So I’ve been monitoring my periods the last couple months. I am a self diagnose pcos, if that makes even sense. I’m too scared to go to the doctors but anywho, but I got all the symptoms of it. when I get my periods I mostly spot and 1 day bleed really light and then spot for the next 2 days. So last month I got my period 3 days late and this time it’s been five days. Yes we’ve been ttc. Has anything like this happened before with anyone? Should I just get my a$$ to the doctors. Lol
