Late Period

So I havent had a period in almost 2 months and I dont know what to do. Im not sexually active so I cant be pregnant but I dont know what else could be affecting my period. And im too scared to go to a doctor because I have never been to an obgyn before. Any tips or possible reasons for this?

Update: After 4 months Aunt Flow has arrived 🥳🎊. I have never been so happy to see this bitch my entire life!!
