I had sex on Feb 1st this month and I took plan b the very next day, now the box says people over 165 shouldn't take it cause it's not as effective. . But I'm 205 ... . Today's Feb 12 , that's 10 days . I still haven't got my period . I feel like I have bubble guts , I am sometimes dizzy/lightheaded , I get tired . I dont really have nausea like I said I get turns in my stomach like it's bubble guts. I'm scared . I don't want to be pregnant at all .. Im freaking out . I don't know if its the pills side effects that are causing me to feel this wag or not . Please help ? I need answers :(
