Has anyone taken a pregnancy test and it came out pregnant but you were not pregnant?? Pls comment

yea before I had my baby, about year in half ago my test were becoming positive but I wasn't pregnant that's when I just gave up cause when it gives you A Bfp and you find out your not messes up your emotions like I said I gave up trying but couple months later I got pregnant without even trying or thinking about it ... and I took 3 test 2 clear blue and then a cheap one from Wal-Mart and ➕ I got 😞 damn test that's why now I don't go by a test anymore for me to find out I'm really pregnant I rather do blood work
