Patient's question:
NoDoctor's answer:
For early pregnancy, a positive result can usually be detected 5-7 days after a missed period. The color change from light to dark represents a progression from weak positive to strong positive, which typically takes about a week to occur. If you have a weak positive result on a urine test after a 35-day delay in menstruation, you can retest again in about a week, around the 45-day mark. If it is mainly pregnancy, the result is usually strong positive. Wishing you good health.
