Why am i slightly disappointed?

I’ve got a 2 year old and a 9 month old already. My husband and I have been using protection during sex to avoid another pregnancy but one night we thought the condom might’ve “broke” or had a hole in it or something. So when my period didn’t come almost 2 weeks ago like it should’ve, I thought of that night. It scared me and I thought “there’s no way we could have another baby now” and I tested...3 times now. All negative. And I feel like I’m slightly disappointed. Maybe it’s not disappointment that I’m not pregnant, it’s disappointment that I still haven’t started my period and don’t have a reason. I haven’t been this late (and not pregnant) since before I got pregnant with my 2 year old 🤷🏻‍♀️😩
