No it would not, when they test for those stds they simply swab the inside of your v*gina with what looks like a giant cotten swab and send it to the lab. If you may be pregnant you need to ask them to do a pregnancy test and they may have you pee in a cup or take blood.
i ment to say , would the nurse be able to tell if the girl was pregnant? like see a fetus or something weird?
It would tell you if you had chlymidia or gonoreah...what else would you expect it to show?
