Weird question im just curious lol

So i saw on tiktok someone took an ovulation test close to their period like 2-3 days away and the ovulation test because she didnt have a pregnancy test on her person at the moment and it came back like almost positive, if that makes any sense. Is there a chance ovulation test taken that late could pick up on pregnancy?

or do some people just ovulate that close to their period?

im generally just curious lol
