As impossible or nightmarish as it may seem, it turns out that women can actually get pregnant while waiting for a baby.
Called superfeiting, while rare occurs when a woman’s egg is fertilized by sperm while another fertilized egg is already growing in the womb.
While doctors still do not know exactly why this happens, it is believed that an increase in reproductive hormones is a key factor.
There are a handful of documented cases of what is happening in people and according to a French study in 2008 there were less than 10 documented cases worldwide.
He was referring to a case study in which a fetus was noticeably smaller than a twin fetus in the same mother, which doctors attributed to one conceived after the other.
A French study in 1992 followed the case of a 32-year-old woman who was pregnant with two babies who were four weeks apart.
When they were born, one was one month older than the other, leaving doctors baffled.
The woman experienced a normal cycle of 28 weeks during her pregnancy and doctors believe that her second baby was conceived after her second menstrual cycle once she stopped taking contraceptives.
The twins grew at a normal rate for their age, but they were born at the same time, which means that the baby conceived in second place was born premature.
In another case, an Australian woman who thought she could never get pregnant gave birth to twins conceived ten days apart, the BBC reported.
Kate Hill was receiving hormone treatment for polycystic ovary syndrome, a condition that prevented her from ovulating.
He seemed to have conceived twins at different times despite having unprotected sex once during that time.
The twins were born with different sizes, weights and gestational development, according to reports.
Experts believe that women who are receiving hormone treatment to increase fertility during IVF are more susceptible to superfunction. This is because your ovaries are being stimulated in preparation for a baby.
