Ovulation can be calculated by using ovulation test strips and ultrasound to monitor the ovulation period.
1. Ovulation test paper: Calculated from the first day of menstruation, you can use ovulation test paper to monitor on the 11th day, until the appearance of a strong positive, that is, the ovulation period. The criterion of strong positive is the same red color as the contrast line. When there are two red colors on the ovulation test paper, it is strong positive.
2. Ultrasound monitoring: Ultrasound monitoring is generally more accurate. Calculated from the first day of menstruation, to the 11th day of ultrasound monitoring in the hospital, you need to monitor ovulation at intervals of about 2 days, until the monitoring of mature follicles. A mature follicle is 1.8 centimeters or more, and is considered a mature follicle. After the follicle ruptures, the chances of pregnancy are higher.
Patients with irregular periods who want to get pregnant can be regulated under the guidance of a doctor and should maintain good lifestyle habits.
