The emergency contraceptive pill
will cause withdrawal bleeding after about 10 days of usage. If you do not get a withdrawal as expected, you need to go for examination. Do not use emergency contraception
on a regular basis; it is going to affect your normal hormonal
balance and your fertility
. The discharge you are experiencing is not normal; it indicates vaginitis; you need to take medication for this. See your gynecologist for a local examination and appropriate treatment. Good luck.
