Can twins be conceived on different days?

Haha yes its actually a thing, its called superfetation but its super rare. Most twins are conceived around the same time though. I have twins and trust me, two at once is plenty of surprise already.

Oh I never knew this was even possible. So interesting to read. Does it change anything in how they grow or the due date then?

I asked my gynac something similar. She said in extremely rare cases conception can happen days apart, but it almost never occurs naturally. Usually twins come from one cycle, either one egg splitting or two eggs releasing together.
