When sperm and egg combine, when can an ovulation test strip detect a strong positive?

Patient's question:

No

Doctor's answer:

If it has combined, then it means ovulation has already occurred. Generally, the positive result on an ovulation test will weaken, so I consider that it has not combined yet. I suggest you continue to have intercourse and try to conceive, as this is the best approach. Waiting for the ovulation test to turn weak positive is not advisable. This pattern of ovulation is characterized by the weakening of the test result.
