Can I get Botox while Pregnant? And if I wait, while Breastfeeding?

I just found out two days ago that I’m pregnant while my appointment for my first Botox touch-up is scheduled for next week. Do you think it’s still safe to go on with it? Can it harm my baby? From what I understand the product should only stay local, in the affected area, and not travel throughout my entire body. I hope I don’t seem extremely irresponsible right now because I’m actually very scared that I could do something wrong and mess up my pregnancy. I really hope you will be able to provide me with some information. Thank you.
