I had unprotected sex on Thursday. I took 1pill for the next choice birth control about 30 minutes after and the 2nd one exactly 12 hours later . I came on my period today (tuesday) is there any possibility that I may be pregnant?

I don't quite understand..
But if you have been taking your birth control pills regulary and been getting your peroids on the Right time I don't think your pregnant...
But in order for birth control pills to work efficiently you need to take them daily and not skip or miss. You should also use more than one way of protection. Birth control is not 100 prevent effective along with all other methoids.
Hope I helped some!

I'm assuming you took a morning after pill just member that those are not always 100% just as nuttin else is either but its way 2 soon 2 say if your actually pregnant or not wait 3 2 4 weeks & then take a hpt
