Thanks for posting your query at DoctorSpring.com
SInce you have not had intercourse, you could never have been pregnant !
That is a plain, simple and indisputable fact.
I will like to assure you, there is NO WAY you could be pregnant without having proper sexual intercourse.
And since you have not had it, there is no question of a pregnancy.
Hence, there is no question of trying to find out if you were ( for somebody who had conceived following intercourse, there is no way of finding out if she had conceived / miscarried so many months back ).
Also, there is no need to have regular Pap smears until you are sexually active.
Feel free to discuss further,
