Delayed period for 10 days

Hi,

I had my last period on Aug 30 and had unprotected sex on September 5 but he did not ejaculate inside.

I took an ipill (Emergency contraceptive pill) within an hour of contact.

I have done 4 home pregnancy test and all re negative..

Today is october 10th and i still did not have my period.

I have tried loads of papaya and anjeer but no periods yet.

This is freaking me out..

Please suggest if this is normal and how accurate are HCG home tests and when can i expect my period and what can i eat to get my periods faster..

Please advise and address at the earliest.. :(

Thanks,
