I have an itchy lower body, and my underwear is always yellow. What's going on? How do I read the pregnancy test strips?Doctor's answer:
Positive: Two red bands appear. One is in the control area (C), and the other is in the test area (T), indicating pregnancy.Negative: Only one red band appears in the control area (C), and no red band appears in the test area (T), indicating no pregnancy.
Invalid: No red band appears in the control area (C) within 5 minutes, suggesting a test failure or an expired test strip.
