How long it takes to get pregnant after intercourse is not determined by one’s own will. If you have intercourse at the time of ovulation, the sperm and the egg will probably unite and form a fertilized egg on the same day. You can detect pregnancy by blood HCG about half a month after intercourse, so the time of pregnancy is not something you can decide, but the time of intercourse can be decided by yourself. If you plan to get pregnant, you can improve your chances of getting pregnant by arranging your sex life during ovulation, because after the egg is ovulated, the survival time is 24 hours, and the sperm survival time is relatively longer 2-3 days. Therefore, a reasonable arrangement of sex during the 8 days of ovulation can effectively improve the chances of pregnancy. In clinical practice, if you plan to get pregnant, it is recommended to start taking oral folic acid tablets 3 months in advance to prevent fetal neural tube malformation.
