A member asked:
Will hpts still be able to detect pregnancy 18-20 weeks after sex/conception or will the hcg levels have already gone down by then?
A doctor has provided 1 answer
Tests are accurate: Home pregnancy tests are very accurate, but if done too early, a negative result may be due to testing too soon. A correctly done urine test will give a reliable result by 3 weeks after sex or 1 week after missing a period. A woman can repeat the test if she did the first test too early, such as less than two or three weeks after having sex. If pregnant, tests are positive until AFTER delivery.
