Given that Kylie just gave birth last Thursday, some are speculating whether the couple got inked while Jenner was still pregnant. According to the American Pregnancy Association , the main risk of getting a tattoo while pregnant is contracting an infection, such as Hepatitis B or HIV, so it's vital to go to a registered practitioner who uses sterile equipment and maintains a pristine working space. There is not sufficient research on how the dye could affect the baby's development, according to the organization, but many pros suggest waiting until giving birth to be safe.
