Levonorgestrel
emergency contraception
"I have used this product 4 times and each time it has been very effective. The side effects aren't that bad, the worst that happens is stronger cramps on your period and fatigue. Your period may come a couple days after you take the pill or it may not even come that month however you shouldn't stress because stressing will delay it even more. This product is great and if taken correctly you should have nothing to worry about."
