Patient's question:
Sperm can survive in the body for 2-3 days. If intercourse occurred on the 1st day, and ovulation test strips showed a strong positive on the 4th day, while a strong positive on ovulation test strips indicates ovulation within the next 24-48 hours, then is it possible to conceive? Is the fertilization of the egg actually at the time the ovulation test strips show a strong positive, or 24-48 hours after showing a strong positive? What I want to know...Doctor's answer:
When it's strongly positive, it doesn't mean you're ovulating right now, but rather that you will ovulate within 24 to 48 hours after the strong positive. So, when the ovulation test shows a strong positive, it doesn't indicate that you're ovulating, but that ovulation is approaching. It's correct that when the strong positive turns weak, it means you're ovulating! If David's test is not very sensitive and ovulation occurs within 48 hours, while Xiu'er's test is more sensitive and ovulation occurs within 24 hours! It's easy to get pregnant the day before ovulation and within 24 hours after ovulation, so when the ovulation test shows a strong positive quickly turning to a weak positive, it's important to take another test in time.
