Positive pregnancy test after heavy period?!

Hi everyone, I have gotten 4 days of positive ovulation tests in a row, which didn't make sense to me, I decided to take a pregnancy test based on some comments I read online. Both pregnancy tests are positive! how is this possible? we've been TTC for the past 11 months with no luck (my husband has low motility and we've been on treatment with vitamins, Maca and other supplements for the past 2 months), I also got my period on Oct 24th, so getting a positive pregnancy test at this point doesn't make any sense! Before I go to my dr. just wanted to check if anyone else had a similar case as mine? what could be causing this?
