Superfecundity !
Its when 2 ova are released in the same cycle and both get fertilized by sperms from two separate acts of intercourse ....
Superfecundation most commonly happens within hours or days of the first instance of fertilization with ova released during the same cycle.
There is a small time window when eggs are able to be fertilized. Sperm cells can live inside a woman’s body for 4–5 days. Once ovulation occurs, the egg remains viable for 12–48 hours before it begins to disintegrate.
Thus, the fertile period can span 5–7 days. Ovulation is usually suspended during pregnancy to prevent further ova becoming fertilized and to help increase the chances of a full term pregnancy. However, if an ovum is released after the female was already impregnated when previously ovulating, there is a chance of a second pregnancy—albeit at a different stage of development. This is known as superfetation.
It is very rare in humans but occurs more commonly in cats and dogs.
