Pregnant and getting teeth pulled?

I am 3 weeks and 5 days. I got braces on three days before I found out I was pregnant. Because my mouth is small I need to have two top teeth pulled, I want to get them  pulled April 1st during spring break so I don't have to take any time off. My first baby appointment is not until April 8th. I tried to talk to my doctor about getting my teeth pulled, but they won't talk to me because I have not had my first appointment with them. Is it safe to get my teeth pulled?
