My pregnant text is opposite. the control line is extremely lighter then the test line. i tested three times in a few days and the get the same result. is it confirm pregnant? my period is delayed for 8 days and i feel seriously sore back?

Tests are accurate: Home urine pregnancy tests are very accurate by 3 weeks after sex. If testing over a few days, and getting positive lines, the tests are considered positive even if the control lines are faint lines. One can contact her primary care doctor (or her Ob-Gyn doctor if she has one) to ask what the next step is. Usually, women take their prenatal vitamins and schedule an appointment with the doctor.
