Sex during ovulation: counting from the first day of the next menstrual period, counting down 14 days to the day of ovulation, the five days before and four days after the day of ovulation together is called the ovulation period, during this period, we should ensure that we have sex every other day. 3. Normal follicular development: when the follicle is about 18-23mm in ultrasound examination on the 14th day before menstruation, it means that the follicle has matured, and it is necessary to make sure that you have a sexual intercourse every other day during this period. 4. Tubal patency: the fallopian tube is the place where sperm and egg meet, if the fallopian tube is impassable, the sperm and egg can’t meet, which will affect pregnancy. 5. The endometrium is suitable for the embryo to implant: after the sperm and egg meet to form the embryo, it takes about seven days to enter the uterus, looking for a suitable location for implantation in the uterus, breaking through the endometrium to implant and implantation, and the thickness of the endometrium at this time is more than 7mm.
