A Bangladeshi woman who was unaware she had two uteri gave birth twice, one month apart.
Arifa Sultana, 20, knew she was pregnant and gave birth to baby at Khulna Medical College Hospital in February, according to officials at Ad-din Hospital in Dhaka.
Then, 26 days later, she unexpectedly went into labor again.
Doctors at Ad-din Hospital discovered Sultana was pregnant in her second uterus, due to a condition called didelphys. After an emergency cesarean section, she gave birth to twins.
"When the patient came in, we performed an ultrasound on her and found there were twin babies," Dr. Sheila Poddar, a gynecologist at the hospital, told BBC. "We were very shocked and surprised.
"I have never observed something like this before," Poddar added.
Poddar also told the station that the woman and her family were “very poor” and she hadn’t received an ultrasound before her first birth, which would have shown the three fetuses.
Didelphys is a rare congenital abnormality. How many women it affects is up for debate.
Sultana’s three babies are reportedly happy and healthy.
