I took plan b on the 12th and just now on the 15th (about 3 days later) I'm beginning to feel nauseous and I even threw up after eating my dinner will this effect the pill? was the pill absorbed in my system already? should I take another? I also had diarrhea maybe 12-24 hours after taking the pill would that cause the pill to leave my system? or was it already absorbed is throwing up normal? most sources say if you throw up 2 hours after taking the pill to take another because it most likely wasn't in your system yet but I threw up almost 72 hours later is that okay? I have a lot of unanswered questions
