Whole period is late!!

••Kay•• • Londyn 09.27.16🎀
I took fertility blend 2 days before my expected period which means I took 8 capsules all together. And my period is late! I'm on like CD32. I had sex on CD11 and CD13. I ovulated on CD15. I don't know if just 8 capsules of fertility blend affected my period from coming or either I'm just pregnant. Idk which one it is. When should I test. Can someone help please
