Very small, First, we do not know, how many day cycle you are. So, how many days late are you.

Have you taken any pregnancy tests ?

As you know, the Ipill or morning after pill if taken right away, is not 100 percent, and the longer you wait, the less effective it is. At 2 days, it may be only 50 to 60 percent effective.

After you are 14 days late, try a pregnancy test.

The pill will throw off your period, that will be in the pamphlet that came with the morning after pill, you should read it to familiarize yourself with the side effects of the pill, and also that fact that this pill isn't a 100% guarantee.

The morning after pill is most effective when taken shortly after an unwanted sex act, or a sex act that can cause pregnancy (unprotected sex). At 48 hours (2 days) it becomes less effective, so there is a greater likelihood that the pill didn't work.

Since you had unprotected sex on November 7, and it is now December 26, it would be okay to take a pregnancy test at this time. Use first morning urine with the test. If it's negative, see what happens with your next period. If you miss it, test again or see your doctor about a blood test (more accurate).

Good luck.
