If i had un protective sex and my period is a week late, nothing in my life has changed like stress or diet, and i had white discharge, am i pregnant?

Test: Why stress yourself. It's as simple as taking a home pregnancy test and you will have your answer. Every time you have unprotected sex you run the risk of becoming pregnant. Use protection and be safe!

Late period : If you had a unprotected sex and now having a late period there is a great probability of being pregnant but not necessarily. If you are having a vaginal discharge it could happen in pregnancy but also it could be an infection. Sometimes an infection could also affect your periods. In any case, i would start getting a pregnancy test and getting checked by your gyn provider.
