How many days is it best to get pregnant by staying in the same room?

Patient's question:

Symptom Description: Diarrhea sometimes does not want for several days
Treatment history and effectiveness: Have not seen a doctor
Help desired: Explain for me

Doctor's answer:

The date of ovulation is generally about 14 days before the next menstrual period begins. The first day of the next menstrual period is counted as day 1, and subtracting 14 days from that date or counting backward 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. To calculate it accurately, you need to know your menstrual cycle very precisely, as only then will the estimated fertile window be correct. If you want to get pregnant, you can start having intercourse every other day during the first day of the fertile window. If there are no 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 appears thin and slippery, like clear nasal mucus, and can be stretched into long strands. You can also use an ovulation test kit to check.
