Fluid retention scores (on a 0â4 scale) peaked on the first day of menstrual flow (mean Â± SE: 0.9 Â± 0.1), were lowest during the mid-follicular period, and gradually increased from 0.22 Â± 0.05 to 0.50 Â± 0.09 over the 11 days surrounding ovulation.
Menstrual bleeding lasts 3 to 7 days, averaging 5 days. Blood loss during a cycle usually ranges from 1/2 to 2 1/2 ounces. A sanitary pad or tampon, depending on the type, can hold up to an ounce of blood. Menstrual blood, unlike blood resulting from an injury, usually does not clot unless the bleeding is very heavy. The menstrual cycle is regulated by hormones.
