Cara Weinhold found out she was expecting in March of last year, but a month later, she found out she was expecting again.

According to a Fox 5 New York article, the woman claimed that once the technology informed them that there was another kid, they initially laughed and assumed it was a joke before they discovered the incredibly small “sac up on the screen and heard his heartbeat.”

Superfetation responsible for double pregnancy 

The 30-year-old woman said she simply recalled: “laying on the table and breaking down in tears.”  She was simultaneously joyful, scared, and perplexed. She couldn’t explain how it happened. The woman added that after they received the news, her spouse Blake sat quite impassively in their room and remained silent.

The measurements of the twins’ sacs allowed the doctors to confirm that the two were conceived around a week apart. Although double pregnancies are uncommon, the superfetation process is what makes them possible, according to medical professionals.

Healthline defines a superfetation as a “second new pregnancy” that takes place after the first pregnancy. In essence, due to the possibility of sharing the same birth, kids born through superfetation are commonly thought of as twins. One would need to either ovulate while pregnant or have two uteruses in order to have two pregnancies. Once more, neither scenario seems very likely.

Causes and risks of superfetation 

Despite the fact that it is unclear how these therapies generate phenomena, PregnancyCorner asserts that they are thought to be responsible for situations in which superfetation is regarded to have occurred.

The infants will grow at various stages of pregnancy, which is the most significant problem of superfetation. The other fetus may not be ready whenever the first baby is ready to be born. The younger baby would also run the risk of being born too early.

Additionally, women who have several pregnancies are more likely to experience difficulties such as diabetes during pregnancy, gestational hypertension and preeclampsia, and cesarean or C-section births. The disparity in the two babies’ developmental stages is particularly important for determining when to do the C-section.
