You used protection and it did not fail during the sex,,,, your contact with her was protected, no need to worry about, irrespective of whose blood it was
The blood on the condom and on the bed was her only thats what she said later on and i am not really sure about the condom whether it was intact or not I even called that parlour today and they said they do the medical checkup of girls every week, but how truthful he is??
Had you had a condom failure you would have known without a doubt.
I am sure about the condom but how about the symptoms??
