Can twins be conceived on different days?

1. Conception on Different Days: Twins can indeed be conceived on different days, a phenomenon known as superfetation. This occurs when a woman ovulates more than once in a cycle and has intercourse on different days, leading to fertilization of eggs at different times.

2. Superfetation: This rare event results in twins conceived days apart during an initial pregnancy.

3. Typical Twin Conception: Usually, twins are conceived simultaneously, either from one fertilized egg splitting (identical twins) or two eggs fertilized at the same time (fraternal twins).

4. Medical Rarity: Superfetation is extremely uncommon in humans but has been documented.
