Does anyone else feel this way?

Two almost three years ago (Jan. Will be 3 years) I had a miscarriage with a now ex of mine. (The miscarriage is what tore the relationship apart)

Fast forward to now, I’m currently with someone and we don’t use condoms and I’m not on birth control. We aren’t actively trying but aren’t not trying either. If I ended up pregnant it would totally be fine with us. Because of this, it starts to make me question about possibly being infertile 😞 I see posts all the time about how people use condoms, are on birth control, and etc yet end up pregnant without even trying. It just is something that’s on the back of my mind and wanted to see if anyone else feels this way or has experienced this as well. (Please don’t comment anything negative).
