Ovulation test used as pregnancy test

Crystal

Can ovulation tests detect pregnancy?

I have very irregular periods. My cycle lengths very between 19 and 38 days(most of the time they're between 33 and 38 days) and I usually ovulate between CD 19-22. Right now I'm on CD 38 and I have no PMS symptoms like I usually do but I also don't have any pregnancy symptoms other than just being really tired lately. I just took an ovulation test for the hell of it and it was positive?
