What does this discharge mean?

I had a miscarriage on oct 6 and had unprotected sex on oct 16. My partner pulled out and I took the yuzpee method within 24hrs. Days before the intercourse I had watery discharge and even milky ones. After the yuzpe method ive been dry. A while ago i had pale yellow discharge and now i had this. Ive been having very mild abdominal pain too. What does this mean? Im afraid ill get pregnant again
