Can paps smear on the first/second week of pregnancy cause miscarriage ??

Very very rare: A normal screening PAP should not cause any significant damage to any structures. It is a mild scraping or brushing of the ecto-cervix, outside ,and not the canal or endo, inside structures. A PAP smear is indicated as part of a routine exam for pregnancy. Normally at a pregnancy exam a PAP, cultures of the vagina and cervix are taken. One should refrain from alcohol and tobacco. Good luck.
