I might not be pregnant?

My bf of 3 years and I recently had sex without protection and on my 11% risk of pregnancy and on my 27% risk of pregnancy days.

The only thing that scares me is that sometimes i think i might not be able to have kids. I dont know why i just do. We've never tried. Its more like if it happens it happens thing. We love eachother very much and trust eachother. We used condoms the first year and a half and after that he would just pull out. We do use condoms here and there but its rare. He comes inside of me days before i start my period and when im on my period. Just wanted to vent. Thanks girls
