In pelvic exams, during intercourse or any other normal situation, Paulson said it's difficult to feel that a person has two vaginas. Paulson used an analogy of walking into a tent separated by a tarp down the middle with your eyes closed.
"Once inside, you can't feel a difference in the wall," said Paulson. "A vast majority of the time these things aren't discovered, even in an exam."
The same was true for Hasaj, who said she'd gotten regular annual checkups since she was 18. This new discovery finally explains why every other pap smear gave inconclusive results.
"For the last nine years, I've had so many smears -- possibly 30 different people have given me smear tests," said Hasaj. "The doctors said only thing you would have noticed would be you had problems using tampons."
When she heard that, Hasaj said her history made perfect sense.
"I thought 'oh my god, yes," said Hasaj, who thought something was strange during the previous periods.
"But I never would have guessed this," she said.
