Can I Take Any Medication To Bring On My Period After Sex On Ovulation Day And Gynaecocid Use?

Hi, I had sex on my ovulation day and the next day I took a tablet of Gynaecocid and finished the other the following day. It’s 6days already but I’m yet to see my period just noticed blood that came out a little and stopped. I don’t know if I’m pregnant though I tested myself with a PT strip and it reads negative.. what other drug should I take to push out my menses cos I don’t want to undergo an abortion. I’m so scared though I’m yet to miss my period.
