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

Those poor babies... Being born to Alabamaians in Alabama.
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.
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.
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.
Two utes?
My ex has a bifurcated uterus. Uteruses can be weird.
