Anytime if you wanted to test. Don't be surprised if it's negative though.
My period ended normally and its been almost two weeks since it happened. When should I take a test?
No, but if you don't want to become pregnant don't have any unprotected sex ever. It makes little difference how long he does it for or if he's dry or not.
There could always be a chance your pregnant. Unprotected sex? If you are really stress about it though sometimes your mind can play tricks on you. Take a test when you can, it will releave alot of the worry
