i tested positive in September, went in to planned parenthood and tested negative. havent been using any types of birth control, hes been finishing inside of me for months. haven't had a period but now on thw patch. if i was pregnant, over the amount of time to where it doesn't read on a pregnancy test, could this patch lead to a miscarriage? they also said i should take a home pregnancy test in two weeks.

but will being on the patch lead into birth defects or miscarriage?
