(1) For women with regular menstruation, estimate the date of your next period and then go back 14 days, which is the ovulation period. (2) Observing the leukorrhea can also predict ovulation. When ovulation comes, in the middle of two periods, many women will find that the leucorrhea is abundant, sometimes stretched like egg whites. Another little secret is that before ovulation, the level of extracorporeal hormones rises, and some women will have a feeling of increased sexual desire, so don’t miss this sweet time! (3) Prediction of ovulation test strips. Starting from the 8th to 10th day of menstruation, use this test strip to test your urine every day from 3 to 8 pm. Remember not to drink a lot of water before the test. If the test is positive, the night of the day and the night of the second day are good times to conceive. (4) If you feel that it is difficult for you to do the above, you can also go to the hospital and ask your doctor to monitor the growth and development of the follicles by doing ultrasound, the time to start monitoring ovulation by ultrasound is 8~10 days from the onset of menstruation.
