Levonorgestrel
"I promised myself I would write a review about this as all these reviews sometimes don't have the ending result which scared me even more the more I read. I took the pills within 6 hours (the condom broke) on March 7. Don't take this til you're at home as it made me feel nauseous and dizzy for about 24 hours. Take it and go to bed if you can. 4 days later on the 11th of march  I had a heavier spotting for 6 days! And then finally on the 23rd I got my period which was 4 days early in my cycle but it works! Don't stress too much about it if you take it soon enough!"
