Abortion pill vs. Surgical procedure?

What is the pros and cons? I want the surgical only because I live in a religious household and want to keep it a secret and I also, have a child that I need to take care of. The only problem is that I am scared of having instruments up there? If that makes sense. I had a miscarriage before and know that the pill will be brutal but, again I don’t know if I should risk suffering for a bit. I believe to be about 7-8 weeks. Appointment is on a Saturday.
