My last period lasted till 28 June ,I have unprotected sex on 29 June just after my period again starts but lasted up to 30 June.then I take emergency pill on 30 June after 6 days on 6 July again there is a light bleeding from my vagina.there is any chance that I get pregnant .please help I am very upset .my age is 25

Yes, there is a chance you could be pregnant, the morning after pills is not 100 percent effective. The longer you wait to take it, the less effective.

You are aware of the money side effects, and how it can change, or even dely your period for a couple months.

So no way to tell now, wait till next period is due and see if you miss it or not, if you miss it, wait two weeks to test
