You are quite wrong. There are instances where two eggs are fertilized on separate occasion, because two eggs might have dropped. Research!
there are times when a woman gives birth to two babies, sometimes its obvious that they have different fathers.... like when they have a black baby and a white baby at the same time.
if both ovaries produced each one an egg at the same time and each egg was fertilized with a different spermatozoid from different father, babies can be from different fathers and be born at the same time
it's just that such a case is so so rare, but theoretically it's possible
sorry but i'm annoyed... you can't have both of their babies in one fertilization my dear (if it is the same as girls getting pregnant) it has to be one of the two's sperms, and an egg can't choose (￣∇￣")
but u all can make more babies any other time can't u <3
