Mild to Moderate Dysplasia - LEEP

Hi, I'm 22 and had abnormal PAP smear results a few months ago. I was diagnosed with Mild Dysplasia (CIN I). My doctor sent me to get a colposcopy a month later, and the results were that I had Mild to Moderate Dysplasia, and my OBGYN recommended that I have the LEEP procedure done. I'm worried that this is a hasty decision. I know that the LEEP procedure would basically help remove the affected areas, although of course, there is a chance it could come back. But my first doctor told me that mild dysplasia usually clears itself up if you're young and healthy, and your immune system does its work. Although, I'm also concerned if left untreated, this could progress into more severe dysplasia. Can anybody recommend what I do in this situation? I'm so scared to have a LEEP done unneccessarily in case there are complications like infection or even complications during pregnancy later.
