Why was I prescribed birth control pills?

I'm 33. I'm not having sex.
Somewhere along the lines I contracted herpes. I don't know how or from whom.
I question that diagnosis. About a month ago I had ovarian cyst. It went away. Doctor wants to put me on minastrin low dose. I'm concerned because I want to get married someday an have kids. I fear this will hurt my fertility. Once I asked if it will doctor hesitated but said it won't.
During the Pap smear he put his finger in me feeling for my uterus. He said it isn't swollen. Why did he do this? He wants me to come back in November to see how the pill is. I'm all sorts confused. Is this normal. I believe they're lying about the herpes type 1
