"november 18 i got my period and on dec 3-4th my boyfriend and i hadn&#039;t use protection and i was a little worried because the days happen to fall right smack in my mid-cycle. we use contraceptive but i guess the heat of the moment caught us off guard. on dec 5th at 8pm i took the plan b pill. i did experience some cramping and mild nausea, after taking the pill but nothing unbearable. i waited for my period and on dec 16th... i got it! it was right on time. i am very please with this product."
