Hi..Welcome to HEALTHCARE MAGIC..

I have gone through your query and can understand your concern...

First of all there is nothing to worry as you have taken the emergency contraceptive pill within 72 hours of unprotected sexual intercourse. So most probably your periods are delayed. You have also done pregnancy tests also. So chances of pregnancy are very very less.
The delayed periods are due to high dose of hormone levonorgestrel 1.5 mg contained in emergency contraceptive pill ( morning after pill). Hence your period might be early or late for next two cycles. This is a known side effect of taking emergency contraceptive pill. It is not possible to tell exactly when you will have it.
Please use condoms or other methods of contraception to prevent unwanted pregnancy in future. Taking more than one emergency contraceptive pill in 3 months is not advised & can cause serious side effects like ovarian cysts, ovarian hyperstimulation syndrome, irregular cycles, etc

If problem still persist visit a gynaecologist

Hope this information helps.
