"i took plan b a few weeks ago... ever since i have woken up with a bad headache, acne, weight gain, mood changes, light cramping, nausea &amp; extreme fatigue. 
i probably shouldn&#039;t have taken this as my experience with regular birth control was bad.... only reason i rates as high as i did was because i didn&#039;t end up pregnant. however because of the side effects i will never be taking again."
