I recently had unprotected sex. how long would it be before i can find out anything?

If you ovulated....: If you were ovulating around the time of the unprotected sex, you could be at risk for pregnancy. A urine test will be positive as early as the time of the expected period - but certainly within the month after conception. This would be a great time to check in with your health care provider about reliable birth control so you don't have to sweat this one out! good luck. Lgromkomd.
