"i took plan b after approx. 2 hours after unprotected sex. that same day after a few hours i started to feel very bloated, and felt like that the following day as well. i honestly had difficulties driving since i also had pain on my right ovary area! i got my period 1 week after the pill and 1 week before it was supposed to be. not to mention, but i&#039;ve always gotten heavy period with no cramps...just very bad headaches, they are awful! but girls plan b really works. definitely $50 is really worth it! hopefully this help."
