1. For those who have regular periods, estimate the date of your next period and then work backwards 14 days, which is the ovulation period. For example, Xiao Li, who has regular periods and always has her period on the 15th of every month, her ovulation period is around the 1st of every month. A patient always has her period once every 25 days, and she estimates that her next period will be on the 24th of the following month, so by working backwards 14 days, the 10th of the following month is her approximate ovulation time. In the 3 days before and after the ovulation period, arrange a few more opportunities for intimate contact, and the chance of conception will be greatly improved. 2. Observing the white belt can also predict ovulation.

If the first test is positive, there will be 2 red bars and you will ovulate within 36 hours, and it will be a good time to conceive on the same night and the second night. 4, if you feel that these are difficult for you, then you can also go to the hospital, so that the doctor through the method of ultrasound, monitoring the growth and development of follicles, more accurate prediction of ovulation time, guide the time of intercourse, so that the most objective, scientific na!
