I'm 16 going on 17 and my mom is taking me to get a paps sum. I think that's how you spell it but anyway. I'm scared to go because yes I have had sex. She asked me have I ever had sex because if I don't tell her the doctor will. So is it true the doctor will tell her. I'm going to the doctor Monday and I'm really scared. She wants me on birth control to.

An exam can only tell if you didn't have sex - by an intact hymen.
But a broken hymen doesn't mean you did have sex, because it can break on it's own.

Unless you had sex within hours of a visual exam and show a certain amount of redness/normal bruising inside the labia, then no, no one can know. If you have a swab for STDs along with the PAP smear, and you test positive for a disease that can only be transmitted sexually, then the cat is out of the bag. And lastly, if you are pregnant enough weeks to test positive for that too, more cats out of the bag.

Your mother is a wise mother. If you were using condoms, they have a high failure rate. If you weren't using anything - let's just hope.

It's called a pap smear. Pap test - Wikipedia, the free encyclopedia Why does she think you might have cancer or need a pap smear this early? Usually young women begin to get them around 18 -- or when sexually active. Or why does she think you need birth control? Of course, if you are sexually active (and she knows or suspects it), you do need to have protection from STDs and an unwanted pregnancy. Has she talked with you about this?

No, the doctor cannot tell if you have been having sex.. And you are the patient. He is bound by confidentiality, cannot tell your mom stuff that you and he talked about unless you give permission for him to do so.

If you are having sex, you need to be checked, there is STD and pregnancy to be concerned about. I would imagine your mom suspects you are having sex which is why she is taking you to the doctor.
The word is pap smear.
