I was wondering if anyone knows or has gotten pregnant while using protection?

I had sex with my boyfriend with a condom July 9th. I believe I was ovulating. I know I was for sure the day prior. His first kid was conceived with a condom so im starting to question if it was used properly or if it may have torn a little because im 6 days late. I’ve never been this late before. And Im starting to feel like there’s no sign of a period at all. To go an entire month without a period is not normal for me at all. I lowkey want to ask him if he noticed anything but I’m going to give it til tmw before I test to be sure.
