Unprotected sex three months ago, period was late, had pregnancy symptoms then they stopped, had brown discharge, pregnancy symptoms back. i'm lost.

Take all the: guess work out and take a home pregnancy test if you have missed your period. Take care.

3 Months?: If you have had your period after the unprotected sex, you would not be pregnant. If you still did not have your period, then be sure to check a pregnancy test. if you are not pregnant, then check with your dr to have an evaluation and some testing for other causes of a missed cycle. best wishes.
