How do you know if you’re infertile?

Ok, so I know this is a silly/difficult question, but I want to know so bad if I can can conceive. So I have 4 sisters. All older than me I’m the baby. Every last one has gotten pregnant and had a baby. I have not. Not sure if God was looking out or what. But I don’t know if I can get pregnant. I have had previous boyfriends to cum in me and never got pregnant. Some of them I did take a plan b, but some I did not and did not even know they ejaculated in me until after wards. I have never gotten pregnant. I have a couple hairs grow on my chin and I am scared that because I had my bacterial vaginosis come and go and did not really get treated for the first time I had it that it may have effected me to get pregnant. I am praying that is not the case. I pray so hard because it have been my dream to get pregnant. A couple months ago I had a abnormal pap: the dr said she was gonna run another one on me next year and it comes out abnormal she will take a piece of tissue from me and look over it under a microscope. I just don’t know what to do. I tried to give this matter to God, but as a woman I think daily if I can conceive. I know I am just 22 and have my whole life a head of me, I just want to know.
