Some women experience breast and nipple tenderness during ovulation, which is related to individual nipple sensitivity. The main reason for this is that the nipples and milk ducts are relatively sensitive to estrogen, and as more estrogen is produced during ovulation, the nipples become larger, redder and darker under the action of estrogen, thus deepening sensitivity and causing obvious nipple and breast pain. Usually, after ovulation, the estrogen level decreases and the symptoms of breast or nipple pain can be effectively recovered without the need for special medication. During the ovulation phase, there will be significant hormonal changes in the body, mainly estrogen. Due to the hormonal changes, a series of signs and symptoms will be caused, such as decreased appetite, high sex drive, high energy, increased vaginal discharge, ovulatory bleeding, breast tenderness, and lower abdominal cramping. If the symptoms are not obvious and do not persist, no special treatment is usually needed. Paying attention to the cleanliness of the vulva during ovulation can effectively prevent gynecological inflammation. In conclusion, there are more physiological changes during ovulation, as long as they are not pathological, no special treatment is needed, just pay attention to vulva cleanliness and hygiene, and maintain a balanced physical and mental state. If you are preparing for pregnancy, monitoring ovulation through basal body temperature or urine ovulation test paper can greatly improve the chances of conception.
