Is a strong positive turning weak definitely ovulation?

Patient's question:

No

Doctor's answer:

Hello, if the ovulation test strip shows a weak positive, you need to test once a day. If it shows a strong positive (when both the test line and control line are clearly visible), it means ovulation will occur within 24-48 hours. Generally, a strong positive will last for 2 days, and when it turns negative, it means ovulation has already occurred.
