Help...

Hi everyone. I recently had a miscarriage, but the day of the miscarriage my husband let the whole load out inside of me. (We had sex before I knew I was about to have a miscarriage.) The miscarriage only lasted 4 days, is there a chance I could be pregnant because of that ? I was told sperm can live inside of a woman’s body up to 7 days. Is there a chance I could become pregnant because of this?
