I took the pill at 12pm lunch today and about 4 hrs after, i started getting sick and puking and having diarrhea and stuff. I read about it that having diarrhea and puking will decrease the effectiveness of the pill. I'm freaking out about that. It may not be much but I just wanted to know because my boyfriend and I had sex approx two days ago. help. how does diarrhea and puking decrease pill effectiveness? and am I still good? Thank you
