I have a question about side effects of taking Plan B. I was intimate with a man and when I realized that there was no protection I made him stop. There was no ejaculation. To be on the safe side I decided to take Plan B. One week later I had started bleeding which I read to be normal. About 3 weeks later I did end up getting my period as normal. I took 2 HPT 2 days prior to getting my normal cycle more or less to calm my nerves. Both were negative. I am still experiencing tenderness in my breasts and also slight cramping. I am worried that my hormones are out of control or maybe an ectopic pregnancy? Any advice?
