The most important thing to know is whether or not the leukorrhea has entered ovulation, which needs to be analyzed in conjunction with the leukorrhea traits, but to determine whether or not it has entered ovulation, follicle monitoring is needed, and the results are more accurate.1. Impending ovulation: When the ovaries are about to ovulate in the middle of menstruation, the estrogen level rises, the cervical glands secrete vigorously, and the leukorrhea is transparent, slightly sticky, egg-white like, in large amounts, and a large accumulation may appear as a large pile of performance. At this time, for women with fertility requirements, you can consider intercourse for pregnancy, which is conducive to sperm penetrating the cervix and reaching the fallopian tube to combine with the egg to form a fertilized egg, and the egg has the best fertilization ability within 24 hours after discharge, which can increase the chances of conception; 2. After ovulation: If a woman has a lump of yogurt-like curd-like leucorrhea, it often represents that she has passed ovulation and has entered the luteal phase instead, in which this leucorrhea appears A few days later, most women’s menstruation will resume. Therefore, to determine if ovulation is occurring, follicle monitoring is recommended. Generally, starting from the 9th day of menstruation, an ultrasound is done every other day to determine the growth of the follicles. Based on the growth of the follicles, the monitoring time can be shortened to predict the ovulation period and guide intercourse with a higher accuracy rate.
