I had a terrible experience with Plan B. I took two within 72 hours because I am neurotic and didn't want a pregnancy. Before I thought that you also had 72 hours after you took it to be safe. I know, I know... It's been two months. The first month I had terrible cystic acne and had to get on amoxicillin for a month to calm the excessive infection on my face and neck. Now, I have gained 14 lbs in a month, while working out 5/6 times per week. When will the weight come off???????
