A member asked:
28 days since sex how accurate will a blood test be to detect pregnancy i am also on alesse?
A doctor has provided 1 answer
Very, very accurate: Pregnancy tests are very accurate and not affected by foods, herbs, common illnesses, sexually transmitted diseases, or medications. A correctly done blood test gives a reliable result 3 weeks after sex (2-3 weeks after when conception might have happened) or 1 week after missing a withdrawal period.
