What Are the Chances....???

i took the pill once (only after a couple hours of having sex) and it didn't have any symptoms on me other then on my second dose it made me projectile vomit (haha I was on the bus and had to get off right away). But my friend took it not that long ago and then her period was late and she felt weird, so she went to the clinic to take a preg. Test and the doctor said that it was normal for the pill to screw up your cycle (but i'd take another pregnancy test to be sure about a week or so after your period is due...But keep in mind some women never produce enough of the pregnancy hormone to have a positive hpt test...So if it's still acting weird in a few weeks i'd go get a blood test done to be sure)

emergency contraception is best when taken as soon after unprotected sex as possible. It is most effective within 72 hours after unprotected intercourse. However, it is still effective to about 120 hours after unprotected intercourse. Right after unprotected sex, it is reportedly effective 86% of the time. After 72 hours, it drops to somewhere in the 60% range and at 120 hours it drops far under 50%.

You should still have some protection, though it wouldn't be as good as if you could have taken it immediately after intercourse.

a test now should be most reliable. If it comes out negative again, relax a bit because stress can effect the timing of our cycle. When we're stressing about our late periods we can even start to think that normal bodily aches, pains, or even a cold is a symptom of pregnancy. Most of the time, we're wrong. Take a test now since you've missed your period and if it's negative and you're still not at ease, schedule an appointment with your doctor or at a clinic.
