PCOS OR ENDO?

Hello! I have a doctor's appointment coming up and I know something along pcos or endo is going to come up because my mother had endo and I have ALL the symptoms. So I was wondering is there any tests they can run other than blood? I have an EXTREME fear of blood and needles and got sick and almost passed out because of a paper cut 😩🥴 so is there anything else ? I know blood is the most common / realiable but I'm literally so scared 😩
