Had unprotected sex like many encounters throughout the night and then an hour just before taking the pill levonelle we had another encounter all these where within a 24 hour mark. At what point do I start counting the effectiveness of the pill from the first encounter or the last one. Is taking the pill an hour after too soon. This also happened about 2 days before my period now I'm on day 3 since I took the pill and am having terrible cramps but the period has not come. What are the chances of not being pregnant. How many more days can I wait.
