from what i have read about how pregnancy tests work it should not affect a pregnancy test. tests look for hcg a hormone present only if you are pregnant. here is what i read: pregnancy tests are designed to tell if your urine or blood contains a hormone called human chorionic gonadotropin (hcg). this hormone is produced right after a fertilized egg attaches to the wall of a woman's uterus. this usually happens -- but not always -- about six days after fertilization. if you're pregnant levels of hcg continue to rise rapidly doubling every two to three days. here is the link: <link> good luck!
