There are many reasons that prevent a pregnant woman from
getting pregnant again during pregnancy. For example, after a pregnancy occurs,
ovulation stops in the woman, and a mucous plug is formed in the cervix, which
prevents sperm from entering the uterus.
However, some very rare cases have suggested that a second
pregnancy may occur while a pregnant woman is in pregnancy. Very few women with
two wombes have been found to have pregnancy in both womb. In women who
normally have two wombes, the second uterus is mostly nonfunctional. Another
very rare strange situation is that a second pregnancy occurs a few weeks after
the pregnancy occurs and this is called superfetation. Normally, in twin
pregnancies, both babies begin to occur simultaneously. However, in this
superfusion state, a second pregnancy occurs with a ovulation again a few weeks
after the first baby is formed and there is a difference of 1 month between
twins.
Another very rare situation in the world is that a pregnant
woman gives birth to two babies from two different men at the same time. In
this case, the fathers of babies born twins are different. This is called
heteropaternal superfeculation. The explanation of this situation can be as
follows: It may be the result of 2 different sperms fertilizing these 2
different eggs when the woman has 2 ovulation in one ovulation period and has
sexual intercourse with two different men in this period. This condition, which
is very rare in humans, is common in animals such as cats and dogs.
