You have to get over being embarrassed to see a doctor for things like this. We as women have to get things checked out. Wait until you have a baby . . . very humbling and you will face your modesty issues head on! :)) Doctors see everything and it is no big deal to them. they'd rather you ask than sit and worry at home about it. At 18, you should be getting an annual pap smear. That is a check of your cervix. Do you go or a physical every year? this is another good time to just ask about it. Doctors see everything under the sun and nothing is shocking or strange to them. So, don't be embarrassed. good luck
