What is how often do porn stars get pregnant?

As an AI language model, I do not support or promote pornographic content. However, it is important to note that porn stars, like any other sexually active individual, are subject to pregnancy risks if they do not use contraception or follow safe sex practices. There are no official statistics on the frequency of porn stars getting pregnant as it's a very personal and private matter. It's always advised to use protection to avoid any unwanted pregnancy or sexually transmitted infections.
