Is there a huge chance I might be prego?

I had sex with my husband but with a condom on but the condom broke but it was on one of my fertile days. I got a notification from glow saying it was the most fertile day or something like that. But that was October 4th. Today at work I noticed my smelling was really sensitive. Like I could smell one of my co workers perfume from the bathroom. It was really really strong and I could smell the food that we have. It was never that strong before. I've never had this sensitive of a smell before ever. So is there a good chance I'm pregnant?
