Is there a reason to worry?

I had sex with my bf with a condom and he cummed in me.I always fill the condoms with water after sex to be sure that there are no leaks.However, this time I couldn’t find the condom in the bin because he went to the bathroom before me.We are together for e month now and i am kinda embarrassed to tell him that every time i take the condom out from the bin to check.I’ve used condoms for 2 years with my ex and it never broke.But i am so used to check the condoms that now i am very anxious that it may have broke and not felt it.I am on my last day of period and my ovulation day is on 3rd and i am scared.Is there a reason to worry about pregnancy?
