Plan B did work for me, but it did start my period almost two weeks early...oh well! I feel so relieved! No more unprotected sex for me! The only symptoms I had were period like symptoms. I just wanted to share my experience with others and let you know it works and it is available if you make a mistake like I did. Also, for your information, I didn't realize I could take it within 72 hours (planB one step) and so when I realized that I could still take it, I took it after like 50+ some hours and it still worked!
