Help!!! Am i pregnant?

So I would be 10 weeks pregnant since conception when condom broke. It was the day after my period ended and i took a plan b right away. I then got my period later on and i took a test before and after it ended and they were both negative. Now i’m seeing that some women won’t test positive till 12 weeks???!? Now i’m stressed and paranoid again, any chance i’m pregnant? I have no symptoms whatsoever and i thought getting my period would ease my mind enough, now i’m stressing again. please someone help me calm my nerves. thank you😭😭
