help!!

hey guys, so eve is telling me my fertile window ended about 3 days ago, but my periods been super irregular. last month it was a week and a half late, and this month it came about 2 weeks early and only lasted nearly a day. i’m not sure if having an irregular period screws up my ovulation or if i’m just not ovulating at all, and i assumes i’m not ovulating because eve told me i wasn’t. my boyfriend finished in me, but i’m worried about my periods being irregular that my ovulation is thrown off? should i be concerned or just trust that i wasn’t ovulating like how eve said it’s ended 3-4 days ago.
