Mittelschmerz

 Mittelschmerz and associated symptoms:

mittelschmerz means ovulatory pain seen on one side of abdomen usually, which can occur due to,
- stretching of capsule of ovary during release of ovum,
-contraction of fallopian tubes to recieve ovum,
-contraction of smooth muscle cells on ovary or of ligaments  due to release of prostaglandins,
-irritation of peritoneum due to blood and fluid released from ovarian follicle,
that pain sometimes can cause nausea,

mild spotting or brownish discharge etc can be seen associated with it due to the decrease in level of estrogen during ovulation,
other symptoms like head ache etc may also be due to release of prostaglandins etc during ovulation,
some women may also experience breast tenderness, bloating sensation, water retention, swelling of genital parts etc,
more intense ovulatory pain can be seen in endometriosis and pelvic inflammatory disease etc conditions.

 if  symptoms subsided soon and if that not severe enough to seek medical advice then no need to bother, if  symptoms persist or become severe better to consult gynecologist once to rule out any other possible cause.
