Wisdom teeth getting removed but i could be pregnant?

okay so i am getting my wisdom teeth removed surgically next month on tuesday june 1st. But im really scared because me and my hubby have been trying to conceive and if i am pregnant i don't want nothing to happen to my baby. my last moth period was may 5th. i have an apoimnt in a clinic for a pregnancy test the same day im getting my wisdome teeth removed. but i am really concern because im afraid that the test wont be accurate since it will be on the 1st with 4days left for an actual missed period (which are very irregular). if i am pregnant will the test come out positive that soon? or since its to soon to find out it wont do no harm if pregnant if i go trough with the procedure? please HELP i really don't want to put my baby at risk if prego. but im tinkling if i am maybe ill be too soon to even have an affect in the baby.
