Dear if you had period after unsafe sex, then there are virtually no chances of being pregnant. Sometimes periods are late because of stress, tension, hormonal changes etc. But just to be on the safe side, it would be wise to take a home pregnancy test. Please use condom next time. https://lovematters.in/hi/pregnancy/unsure-about-being-pregnant/unsafe-sex-missed-period-am-i-pregnant https://lovematters.in/hi/pregnancy/home-pregnancy-tests-dos-and-donts If you would like to join in on a further discussion on this topic, join our discussion board, ‘Just Ask’ https://lovematters.in/en/forum
