Hi, I'm 16 years old and had sex for the first time 7 days ago. I took Plan B One Step the next morning and have been experiencing the side effects such as slight nausea, tiredness, and it also cause a lot of mood swings because of the hormones. I have white milky like discharge and I am not sure if that's a sign of pregnancy (read that online) or if that can be another side effect from the pill. My expected date to start my menstrual cycle is in about 2 or 3 days but I'm extremely anxious.
