I am sitting right now with Levonorgestrel Tablets .75 mg debating if even taking it will do anything. I had my last period day one May 17th which makes from the 31st thru today to be the days that I am ovulating, and I know for a fact that I am. I felt it on the 31st, bloating water retention and today stomach craps and bloating. My husband made a mistake today. I am three hours after the fact, and have the emergency contraceptive in front of me. Is it any effect to even do so at this point, I donot want to harm anyone if I do not need to, if it is already to late. I would like to make the best choice.
