The deed is done and you cannot undo it. If you have not suffered any ill effects, you are okay other than that you may get pregnant. Do a pregnancy test 3 weeks after sex. If the result is negative repeat the test in 4-5 days. Use first morning urine and follow instructions for the test carefully. If you do not wish to be pregnant, use contraception all the time, every time.
