A vague pain in the left lower abdomen after ovulation is not something to worry about, it is also normal. Some women do not feel anything when they ovulate, but some women experience vague abdominal pain or mild anal cramping and slight bleeding, which is caused by fluctuations in the amount of estrogen produced in the body. In addition, during ovulation, the leucorrhea increases, with a constant discharge of thin, milky white discharge, followed by a marked increase in watery, clear leucorrhea, like egg white, which also lasts for two to three days. There is an increase in body temperature, and in a small percentage of women, there is also breast tenderness and nipple pain.
