If that is all the sex you had, then no. First, ovulation lasts 24 to 48 hours. If you had sex two days AFTER, then your egg was gone. Second, you used protection. While condoms have a failure rate, it's typically due to breaking. The whole business of tracking cervical mucus is not reliable for anything (taken from a woman who tried for 4 years to conceive and track my true ovulation). So, don't worry about that. Just keep using those condoms! good luck
