Kelsey Hatcher, a 32-year-old mom of three was born with a rare uterine anomaly called uterus didelphys, or two uteruses. However, she was not diagnosed with the condition until last spring, when she discovered she was pregnant – in each uterus.

Hatcher said her husband almost didn’t believe her.

“He said: ‘You’re lying,’ I said: ‘No, I’m not,” Hatcher told NBC News.

Uterus didelphys affects about 0.3% of women. The abnormality forms in the female embryo very early in development, around eight weeks gestation, according to fertility researchers.

    Not a med school student but fraternal twins come from 2 separate zygotes - 2 different eggs and 2 different sperm cells. If you disregard the whole ‘two uteri’ aspect they’d be twins, fraternal twins, dizygotic. It’s all two eggs being fertilized at the same time, right?

        Pregnancy hormone HCG caused ovulation to stop its normal cycle. Essentially, their are either the same age or the first pregnancy already ended and needs to be removed, but due to complications the younger embryo probably won’t make it either.

      According to the article, they didn’t need to be but likely were. Makes sense, thanks.
