Two bars on the ovulation test after ovulation is considered to be still during the ovulation period, which is from 5 days before to 4 days after ovulation. If the ovulation period does not exceed 4 days, the ovulation test will still show a weak or positive result. If the ovulation test is still positive after 4 days after ovulation, it is possible that the ovulation test is out of date or the ovulation test is not sensitive. You can increase the frequency of sexual intercourse during the ovulation period to help improve the conception rate. If the ovulation test is still positive after the ovulation period, you can go to the hospital to have an ultrasound to test the follicles. To ensure the accuracy of the follicle test, when buying ovulation test strips, it is recommended to check the expiration date and whether the package is damaged. After a positive test with ovulation test strips, you can choose to have sex every other day to ensure the quality of sperm and improve the chances of conception.
