What was the longest labor recorded?

Poland resident Joanna Krzysztonek suffered a 75-day labor, perhaps the longest in recorded history, according to the Huffington Post. In 2012, five months into Krzysztonek's pregnancy, one of her triplet fetuses died. This induced her lengthy premature labor.

Throughout the 75-day labor, the physicians instructed Krzysztonek to keep her feet raised above her head and lie in an upside-down position at all times to reduce the pressure of gravity on her cervix, reports Huffington Post. Thirty-two weeks into her pregnancy, she gave birth to two healthy twins. Krzysztonek had to regain her balance after lying in an awkward position and having her feet raised for 75 days, Fox News said.
