Pregnancy normally occurs when a woman has intercourse during ovulation, which is about 14 days before her next period. Women can also test for ovulation through ovulation test strips or monitor ovulation through ultrasound. The chances of pregnancy are usually higher when intercourse is performed within 2 days of ovulation. However, it is important to note that both men and women must be in perfect health to conceive. If the woman has tubal blockage, salpingitis, endometritis or endometrial polyps, etc., the chances of conception will be lowered, or even impossible. If the man has poor sperm motility or low sperm viability, it will also affect conception. Therefore, if a woman wants to get pregnant, it is best for both husband and wife to go to the hospital for a pre-pregnancy checkup, and if there are abnormalities, you can choose to have intercourse during the ovulation period to increase the chances of conception.
