"i took plan b about 6 months ago in august and about 3 months ago in november. i am very thankful that it could prevent me from becoming pregnant but ladies, please, do anything you can to avoid having to take this pill. i understand everyone&#039;s side effects are different but with me, they have been a roller coaster ride. after taking it the first time i experienced the usual side effects of bloating, sore breasts, and some mild dizziness. luckily, i received every expected period. in october i had noticed a lump in my right breast so i went to the doctor and found that it was benign thankfully. so here is why i say avoid plan b. i&#039;m 18 years old, i shouldn&#039;t be developing breast lumps at this age."
