Pregnant?

I had protected sex with my bf but I don’t know if anything went wrong with the condom. Got my period a week after, but it was shorter than usual (3-5 days).

Fast forward to now, I’m 9 days late on my period. It’s been 7 weeks since I had sex. I’ve been testing and they’ve all been negative.

Is there a chance I could still be pregnant or are the test results accurate?
