On which day of menstruation are there dominant follicles

Pregnancy is a very important thing for many people, which leads them to consider more about pregnancy, such as eugenics. Menstruation is a phenomenon of female physiological response. Many people know that women's follicles develop during menstruation. The follicle is what we call the egg. This is an essential thing for women during pregnancy. The prince's strengths and weaknesses will also affect the development of the fetus. So for women, on which day of the menstrual period is the best time for follicle development?

1. How many days after the end of menstruation are there dominant follicles

Generally, the dominant follicle can be seen one week after menstruation, and ultrasound monitoring is more effective. If there is no dominant follicle during continuous monitoring, it may be that the ovarian function is not very good. If there is no dominant follicle during monitoring only on the fourteenth day after menstruation, ovulation may have already occurred. It is recommended that you monitor one week in advance next time, and it is best to monitor every two days.

Second, pay attention to the following points when doing follicle monitoring

1. When monitoring follicles, you cannot stop monitoring as soon as you see a dominant follicle or a mature follicle. You should continue monitoring until ovulation or follicular hypoplasia or luteinization is confirmed.

2. Some people who use clomiphene to induce ovulation should start follicle monitoring the next day after taking the medicine; some people with poor ovarian function have no response or slow response to clomiphene, so they should be careful when monitoring follicles.

3. Follicle monitoring combined with basal body temperature testing can more accurately determine follicle development, ovulation and corpus luteum function.

4. For those with a long menstrual cycle, such as polycystic ovary syndrome, menstruation is often rare, with menstruation occurring only once every 30 days, 50 days or even 90 days. Follicle monitoring can start from the 10th day. If a dominant follicle > 12 mm appears, it should be monitored every day or every other day. If there is no dominant follicle, it can be monitored every 3 days until a dominant follicle appears, and then it can be changed to monitoring every day or every other day. (Note: It usually takes 3-4 days from monitoring the dominant follicle to the follicle maturation and ovulation. Therefore, if the interval exceeds 5 days, the opportunity may be missed.)
