How Many Days After Missed Period Can Period Pregnancy Test Be Positive? Pregnancy tests check if you blood or urine has the human chorionic gonadotropin (hCG) hormone which is released after a fertilized egg is implanted on the wall of the uterus. This process takes six days after fertilization in most cases. The level of hCG continues to increase throughout pregnancy and doubles after 2-3 days. To get a positive pregnancy test, most women will have to wait 5-10 days after their period was due.
