What causes a stretchy clear discharge 4 days after your period?

Menstruation: Close to ovulation you might get those symptoms. Not all women ovulate on the 14th or 15th day of the cycle as thought. If your period comes every 22 days for example, you might ovulate around cycle day 10 or 11 and you might start getting those symptoms you are refering. It depends on how long your cycles are (ruling out any infections of course).
