Uh, isn't that going to be a major complication for all parties involved? For pregnancy and delivery I mean.

They're the same person
Depends on how well formed the uteruses are. If they're both healthy, it should be fine. You would be amazed at the ways a person's body changes to accommodate pregnancies. Idk why this would be any more risky than, say, twins or triplets.
At the Science and Industry museum in Chicago they have/had step by step see-through models of a woman's guts before, during, and after pregnancy.
I took a date there and we had a great time. Arrived at that exhibit and we just stood there for a minute, witnessing how jumbled up the post pregnancy innards were.
I said, "I'll never do that to you."
She said, "Thank you."
Haha yeah, pregnancy can be amazing from an objective "wow, humans can really do that, huh?" perspective and also horrifying from a subjective "I'm sorry, you said my intestines are where??" perspective 🥲
As someone who decided to be pregnant for the first time right now, I definitely have a healthy heaping of both—at the same time even! It's a wild and sometimes darkly hilarious experience.
I'm thinking delivery has got to be way more complicated? The hormones that trigger childbirth might trigger both? But maybe with a special c section everything will be fine?

For med school students who waste time here. A question.
These are not technically twins, right?
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?
What happens if the pregnancies were, say, 5 months apart? What kind of complications would there be?
A natural birth consists of a bunch of hormonal changes that initiate the process (similar to a medically induced abortion); I’d be super surprised if the younger fetus doesn’t abort when the older one is birthed on time.
I was going to ask if other animals were capable of multiple simultaneous pregnancies, but then I figured I should probably just google it.
Interestingly I found that it has indeed happened to humans, but it confirms your idea, because in the latest documented example, the children were born at the same time.

That does not necessarily preclude the younger child's survival after delivering the older child via C-section though. Presumably if the aim was survival of both fetuses that would be the route taken?
I'd be more curious how that second pregnancy even happened though. AFAIK a natural conception isn't usually possible during pregnancy because no eggs are released. It might be possible via IVF or something, but who would you take that risk?
If they went that route, they’d probably have to block the hormonal pathway associated with labor induction anyway (because as the older fetus ages it will start that cascade toward the end of the pregnancy). Theoretically, I bet you could deliver the oldest with a c-section followed by another’s few months later, but you’re really putting the mother’s life at risk because the healing time between c-sections being 6 weeks at minimum. Continuing the second pregnancy for another 5 months could cause internal bleeding.
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.
It's all two eggs being fertilized at the same time, right?
According to the article, they didn't need to be but likely were. Makes sense, thanks.
Though would they end up being delivered at the same time?
Basically, they are only twins if they are born on the same day, because the concept of fraternal twins is basically being born from the same woman on the same day. Identical twins with the split egg after insemination are the only real "twins" biologically (except clones, generally illegal). There's also roman twins, but those are pretty rare, because it involves a woman releasing two eggs but having intercourse with two different men in a roughly 48 hour time period, resulting in half brother fraternal twins.
Wombo combo
My ex has a bifurcated uterus. Uteruses can be weird.
My body tries to grow extra uteruses, but can only make the inside bits, and attaches those bits wherever it wants to.
Gotta love endometriosis.
This is wild.
