Miscarriage, yuzpe, cramps

So i had a miscarriage last oct 6 and i had unprotected sex with my partner on 16 (withdrawal). I took the yuzpe method on 17 within 24hrs after the intercourse. I had milky discharge a bit watery consistency before the intercourse. After the yuzpe i was dry for a day and had pale yellow discharge. Now i am having watery discharge sometimes clear sometimes milky. But i keep having having mild cramps ever since. What could it mean? Im not ready to be pregnant again
