In june month around 12 or 14 me and my girl tried to have safe sex wearing a condom but due to pain she was not able to have an intercourse and she is virgin and I had my condom on so we stopped after 10 min cause it was not going well. In the month of July she had her periods as she always have in the 1st week. And now in august she had her period on 8 but for one day and it was very less but she claimed it also have been once like this. But after june we did not had sex or tried to. I'm worried can she be pregnant if she had only one day period that to less as regular.
