HPT or not?

Roxanne • 25 years old. Married. Mother of two and another on the way... 🙏🏽
So I been ttc this month, and AF is supposed to come on July 12.. and this weekend my family is going to the casino, where there is a lot of smoke.. I don't know if I should go because I don't want to harm my pregnancy if I'm pregnant. Can I take a HPT on friday? Or is it too early?
