Repeat Pap Smear in 3 Months?

Hello everyone,

I just received my biopsy results today. My biopsy results showed low grade cellular changes, which is the same result I have gotten before the last time I had a cervical biopsy done. However, my doctor said that during my colposcopy, my cervix appeared to show more moderate changes rather than low grade changes. Apparently, based off of her observation of my cervix, she was not expecting a low grade result. She wants me to come back in 3 months to have a repeat Pap Smear. Is this common and should I be worried?

Thank you!
