Patient :I had unprotected sex and took Plan B One-Step almost exactly 6 hours later. I am 18 years old and I weigh 180 pounds and I am 5'3 1/2. What is the efficacy of Plan B for me? Do I have any reason to be concerned? I have a very irregular period and have no idea when I ovulate or start menstruating.
