Question 6

are urine pregnancy tests accurate? its been 32 days since sex, would the negative result be correct?

Accepted Answer

: Home pregnancy tests are very accurate and not affected by foods, herbs, common illnesses, sexually transmitted diseases, or medications. A correctly done urine test gives a reliable result 3 weeks after sex (3 weeks after when conception might have happened) or 1 week after missing a period. If done sooner, a positive result is likely real, but a negative result may be due to testing too soon.

Yes: Each kit is a little different but there is usually a control line that is always there and a line next to it that is there if the pregnancy test is positive.

Question 9

how do pregnancy tests work?

Accepted Answer

Measure hormones: Pregnancy tests measure the level of a hormone called human Chorionic Gonadotropin (hcg), which begins to be produced when the fertilized egg implants into the uterine wall.  This hormone can be measured in urine or in the blood.  The blood test is the more accurate of the two methods.
