I had unprotected sex on 5th May after that I took I-pill within 30 min of the act. After 3 days on 8th May I had bleeding which lasted for 4 days. In the next month I had periods on 7th June which were delayed by 6 days from my normal periods date. But the periods were normal and it lasts for 6 days as usual. Is there still any chance that I am pregnant..

Doesn't sound like it, but if you are concerned then an HPT or doctors blood test would be in order.

All signs point to no, take a pregnancy test though with first morning urine to be 100% sure. Delayed periods can be caused by many things, including stress.

As you know from reading all the information on the pill and discussion with your doctor about birth control, that the morning after pill will effect your cycle and can cause bleediing like you have had. This sounds like one of the side effects of the pill.
