Abnormal?

I had a scheduled appointment with my OGBYN doctor to get birth control and I also ended up getting a Pap test, it was my first Pap test. He said told me if I didn’t get a call 10 days later that would mean everything is fine. My OGBYN doctor tried to get in contact with me 10 days later, on Thursday but my phone was off, so I called Friday, none of his nurses were working that day. I called back in Wednesday and they told me that I tested negative for 3 std’s. Then they told me my Pap test came back abnormal. I got worried. I didn’t know what that meant. She said they needed to schedule another appointment to see if it’s nothing cancerous. I looked up abnormal Pap test and I read that HPV is the cause of cervical cancer. It also creates warts on various parts of the body, but I’ve never seen or felt warts anywhere on my body. What does this mean? Am I overreacting? What can I do to make sure? I don’t see my OGBYN til next month.
