I had unprotected sex a week ago and want to know if I am pregnant can I take a home test?
Whether you have had planned or unplanned unprotected sex, once it has happened women are obviously very keen to know whether it has gotten them pregnant or not. However a fertilized egg does not mean a pregnant, even if the unprotected sex resulted in sperm fertilizing the egg, that egg then needs to travel to the uterus and that can take between 6 to 12 days or so. Therefore though there are sensitive tests that allow you to test early for pregnancy at home, a week after the unprotected sex may still be too early.
A home test looks for the pregnancy hormone called hCG which the body starts making when the fertilized egg implants into the uterus. While it is possible the egg has reached the uterus a week after sex, your hCG levels are probably far too low for even a sensitive urine test to detect. Some women can get an accurate result, but most need to wait at least another 7 days, and for the best accuracy testing should be done around the day of your missed period.
