How To Correct The Misuse Of Medicine?

I made a mistake of taking postinor a day after I had my period because I had unprotected sex. 6 days after, my period came back again. Saw a Doctor and he gave me Primolut N 1 x 3 for 5 days. It stopped but 2days after completing the dose, my period came out and I'm on the third day. Is there anything I can do to correct this?
