Is it weird

Is it weird to think that I can’t get pregnant? Even if I have a period every month comes around the same time every month I also get ewcm two days before ovulation etc like the normal for me. But I honestly STILL feel like I can’t get pregnant lol. So many of these pregnancies happen unexpected and I feel as if all those times I’ve had unprotected sex that it never happened to me. I feel like it would’ve happened by now. I mean I probably do ovulate I get my period every month PMS symptoms every month nothing really wrong with my body I just always have that what if I can’t get pregnant really. I’m not ttc but I still feel like I would’ve been pregnant. Anyone else feel this way besides me? lol
