Doctors in Utah are confirming that a woman is carrying two babies at once that are not twins and that have two different due dates.
Angie Cromar has a rare medical condition known as didelphys which means she has two uteruses.
As a result of her condition the 34-year-old conceived twice and is carrying babies that are just a week apart.
An ultra-sound showed that one baby is six weeks and one day, the other five weeks and four days.
Cromar, a labor and delivery nurse, knows the rarity can bring about complications like pre-term labor and low birth weight.
This is not her first pregnancy but she says her two uteruses never caused her any issues in the past.
Only about 100 people in the world are known to have given birth in this way.
