Biopsy?

I went in for an annual Pap smear last week, and I thought everything was fine. I haven’t had anything wrong with me, and my doctor said my cervix looked healthy. I got a call about two days later saying that my std tests came back negative, and I figured that was it. Well, the office called me again a few days later. The woman on the phone told me that my Pap smear came back as abnormal and that they wanted to schedule a biopsy. I’m only 21 and I don’t understand why they immediatelyjumped to a biopsy, rather than just monitoring it. They also called me multiple tomes with different test results, which I thought was so weird because they usually don’t call for negative results, and you’d think they’d call once with both results. I’m just so confused. The woman who called and told me I needed to schedule a biopsy told me I have HPV, which I didn’t even know. Nobody told me that, and I didn’t receive a call or letter, she just casually threw it in during the conversation. So obviously, I’m super upset. I’ve been crying off and on because I’m honestly terrified that something is really wrong with me. I don’t know if the cells seemed really abnormal and that’s why they want to do a biopsy; I have no idea. But I’m really scared and I don’t have anybody I can talk about it with. My mom and I aren’t close and I don’t want to tell my boyfriend yet because I’m terrified of how he’ll react. I’ve never slept around, but I recently found out the guy I was dating a year ago cheated on me multiple times in our relationship, which now makes me feel like this is why this is happening to me. I just feel like the doctors office isn’t communicating with me.
