So I don't believe I felt sick when I took Plan B right after. I've heard that a lot have been feeling sick a day or a few hours after. I'm just getting these symptoms now of bloating, nausea, sometimes headaches, sometimes breast hurt, sometimes dizzy, and I'm curious to if it can go farther than a month? I've also had leg/thigh cramps. I was wondering if it did sound like pregnancy or not. So my main question is: how long can the side effects for Plan B go on for?
