Could The Use Of Contrapill Cause A Delay In My Period After Unprotected Sex The Previous Day?

Hello Doctor, I had unprotected sex on the 9th of March, 2023, I was supposed to see my period on the 10th of March, so I used contrapill on the 10th of March, but since then I haven t seen my period. Could contrapill be the cause of this delay in period? I ll be glad if I can get a quick response from you. Thanks.
