Ovulation

Hey.. so I’ve noticed recently maybe a year or less.. that my periods have changed.. I went from 28 day cycle to anywhere between 30 & 41 days.. and I’ve been beginning ovulation RIGHT after my periods end.. like I ended my period yesterday and today I’m ovulating.. I know this because I woke up with ovulation cramps so I took my temperature it was 36c and I took an ovulation test and there was a little faint line there.. I’m just curious though.. is there still a chance I could be infertile even though I am and have always been ovulating?
