How long does it take to detect pregnancy after a late ovulation?
Testing for pregnancy can be conducted within 1 to 2 weeks after late ovulation. Women with late ovulation can detect pregnancy through HCG testing approximately 1 to 2 weeks after ovulation, provided they have intercourse during the ovulation period. If ovulation has not occurred or occurs late after intercourse, the sperm will wait for the egg in the fallopian tube, where the sperm can survive for 2 to 3 days.
1. The lifespan of an egg is 1 to 2 days, with its highest fertilization ability within 24 hours after ovulation. In contrast, sperm can survive in the female reproductive tract for 2 to 3 days. To maximize the chances of conception, it is recommended to have intercourse during the ovulation period, as the chances of conception decrease as you move further away from the ovulation period.
2. If you have intercourse during the ovulation period, you can collect morning urine approximately 20 days after intercourse to conduct a pregnancy test.
3. When intercourse occurs during ovulation, sperm takes approximately 1.5 to 6 hours to reach the fallopian tube and combine with the egg to form a fertilized egg. It takes an average of 9 to 13 days for the fertilized egg to enter the uterine cavity. After entering the uterine cavity, it does not immediately implant but floats for 2 to 3 days to find a suitable location for implantation.
4. After the fertilized egg implants, trophoblastic cells begin to secrete blood HCG. Urine testing is best performed 20 days after intercourse as the HCG level in urine is lower than that in blood. If blood HCG testing is used, pregnancy can be detected 15 days after intercourse.
