My girlfriend and I had sex for the first time last month on the 24th of October. I ejaculated inside of her, but I was wearing a condom. She didn't experience any bleeding after sex. However, she did experience bleeding 3-4 days after (on 28th October). The bleeding lasted 2-3 days. Her periods generally happen in the last week of the month or the first week of the next month. However, she has not had her period till now (30th November). Is there a chance that she could be
pregnant? Was the bleeding that she had on 28th October for 3 days her period or was it because she lost her virginity?
