Condom break

So I had sex with this boy yesterday. During sex I heard a pop and didn’t think anything of it. The next day(today) when I used the bathroom when I wiped I found the tip piece of the condom had broke off. From what I know he did not cum in the condom.

I have been on the pill for 5 months and have taken them everyday plus was on my period the day before we had sex. Is there a chance I could be pregnant? Should I be worried?

Also I think he knew the condom broke and didn’t tell me.
