Despite being one of the most natural things in our world, pregnancy is still a pretty huge deal, especially if you’re pregnant with more than one child. When carrying two babies in a cramped little womb, complications can arise very easily.

However, most people won’t experience any pregnancies as complicated and bizarre as Jessica Allen’s.

You probably didn’t think it was even possible to become pregnant when you already have a bun in the oven, but apparently it is! That’s exactly what happened to Jessica: she fell pregnant twice within the “same pregnancy”.

Ultimately she gave birth to two babies at the same time, but because they weren’t conceived at the same time, they weren’t twins.

In fact, they weren’t even full siblings, or half siblings… The strange thing is, they weren’t even related at all!

The newborn babies had two entirely different parents! But how is that even possible you ask?

Well, it all began when Jessica, a 31-year-old mom from California, decided to undergo IVF in the spring of 2016. It wasn’t the desire to have children of her own that triggered her decision to receive the fertility treatment. She already had kids with her partner, Jasper, and was simply looking to earn money from being a surrogate mother.

According to the New York Post, she became a surrogate for a Chinese couple who were willing to pay her $30,000 for her services.

Not many people are aware of this fact, but California is actually one of the few states in the US which legally allows women to earn money by carrying out a surrogacy pregnancy.

Then Jessica found out something extraordinary when she was about six weeks pregnant. She attended a routine ultrasound, but wasn’t expecting to hear anything other than how the baby was getting on. Whether or not he or she was developing in the right way, if he or she appeared to be healthy etc.

The very last thing Jessica was expecting to hear from the doctor was that she was pregnant with twins! When the biological parents were alerted to the news, they agreed to increase the initial $30,000 to $35,000. They were thrilled at the prospect of becoming parents to twins.
