How often is it best to have sex to get pregnant

Patient's question:

Symptom Description: Occasional diarrhea that sometimes doesn't occur for several days
Previous Treatment and Effect: Have not seen a doctor
Help Needed: Explain it for me

Doctor's answer:

The ovulation date is generally about 14 days before the next menstrual period. Starting from the first day of the next menstrual period, subtracting 14 days or counting backwards 14 days gives the ovulation day. The ovulation day, along with the 5 days before it and the 4 days after it, together constitute the fertile window.
For a more accurate calculation, you need to consider your menstrual cycle, and it must be very precise for the estimated fertile window to be correct. If you want to get pregnant, you can start having intercourse every other day during the first day of the fertile window. Without any special circumstances, pregnancy is usually achieved.
During the fertile window, a woman's basal body temperature may be slightly higher, and her cervical mucus often resembles thin, clear mucus that can be stretched into long strands. You can also use an ovulation test kit to check.
