Cervical biopsy

I have hpv. The kind that cause cervical cancer. My hpv is low grade. I found out last April. When I found out my Medicaid just ended and my job insurance is too high. The community clinic wanted me to pay 400 all in once. So I couldn't get the biopsy. I'm a single parent. I keep pushing it off. I do plan on getting it done since its tax season and I will have the money then. Do you think I've waited too long? Does it progress that quick? It's been almost a year since I've found out about the hpv!
