Normal post operative bleeding lasts from several days to several weeks after surgery. After the first couple of days the bleeding turns into spotting, usually dark red but sometimes bright red. Then in most instances, the bleeding stops for good. Sometimes there may be a burst of bleeding at about 2-3 weeks if there was a collection of blood clot in the pelvis from right after the surgery. And occasionally at about 2 - 8 weeks after surgery, there may be some bright red vaginal spotting due to suture dissolving.

For example, if you weighed 175 pounds you would multiple that by 2/3 and learn you should be drinking about 117 ounces of water every day.
