dear Ms, this minimal fluid accumulation is a sign of mild inflammation . it is recommended that you take an anti inflammatory as ibuprofen tablets 3 times daily for one week and repeat the ultrasound scan . the upcoming period is not the cause of that fluid accumulation

Hi & Welcome.

Incomplete data like purpose of doing ultrasound, any associated symptoms like fever, lower abdominal pain, irregular menses, infertility, etc???

The pouch of Douglas (POD) is a localized area of the peritoneal cavity located between the back wall of the uterus and the rectum. It normally contains 1 to 3 milliliters of fluid throughout the menstrual cycle which increases to about 4 to 5 milliliters during ovulation.

Minimal free fluid (up to 5 ml) in POD in absence of associated symptoms can occur under normal conditions when a woman is ovulating.

It can also be due to ruptured ovarian cyst, pelvic inflammatory disease, pelvic infection, an early pregnancy or any inflammation in the peritoneum involving colon or small intestine.

If you don't have any of the above mentioned symptoms, then there is no need to worry about any risk of getting pregnant.

However, I suggest you to consult a gynecologist and get examined for confirmation of diagnosis.

Hope I could answer your query.

Kindly rate the answers if you are convinced.

Hi & Welcome.

Based on the given report of the ultrasound the minimal fluid in pouch of Douglas could be due to either a normal finding associated with ovulation during the menstrual cycle if you do not have symptoms like abdominal pain, irregular bleeding, vaginal discharge, infertility, etc.

Otherwise it may be due to some abnormal conditions like rupture of
an ruptured ovarian cyst or pelvic inflammatory disease or certain infections involving the colon or small intestines like acute appendicitis.

There is no need to worry as there is no risk in pregnancy. However, you are advised to consult a gynecologist for proper clinical correlation.

Hope the suggestion given above would be useful.
