my g/f and I haven't had sex in a while due to the fact she is off BC(couldn't afford it at the moment). After 2 months of no sex, we both got pent up and got into it. After giving her oral I penetrated her for like a split second before she stopped me. I felt guilty, trust me. That was a two weeks before her ovulation week. She has taken two tests and both came back negative, but she is still worried. Could she be pregnant? How can I comfort her if her tests came back negative and she still worries?
