Free fluid accumulation during ovulation is a normal physiological phenomenon that usually occurs between the 14th and 20th days of the menstrual cycle. Ovulation refers to the time when eggs are released from the ovaries to the fallopian tubes. It is also the best time for sperm to combine with eggs. However, for some, free fluid accumulation during ovulation may become an abnormal symptom.

Free fluid is a vesicle of fluid that forms when an egg moves within the fallopian tube. This fluid vesicle usually occurs between days 10 and 14 of the menstrual cycle, but may occur more frequently between days 14 and 20 of the menstrual cycle.

Under normal circumstances, the amount of free fluid is not large, usually no more than 10mm. If a woman has more than 20mm of free fluid, it could mean a few problems. For example, free fluid accumulation may indicate that a woman has a fallopian tube disorder such as a blocked fallopian tube. In addition, free fluid accumulation may also indicate that a woman has other diseases, such as ovarian disease, reproductive system infection, etc.

Women are advised to seek medical advice as soon as possible if their free effusion exceeds 20 mm and exceeds the normal range. Doctors may give them an ultrasound to determine if other diseases or abnormalities are present. In addition, the doctor may also recommend that they undergo other tests, such as blood tests and X-rays, to determine whether other diseases or abnormalities are present.
