a vaginal yeast infection will not interfere with the accuracy of a urine pregnancy test.
could a yeast infection effect the results of a pregnancy test? . i am 3 days late on my period. i have a yeast infection. with each of my previous 3 children i got yeast infections when i found out i was pregnant. i have taken 3 tests. 1/day for the last 3 days. each one has been negative. is it possible that a yeast infection can give negative results on a pregnancy test? i don't remember this happening before. i think i took the test then a few days later got the yeast infection.
