I took 2 days of my birth control (ortho-tri cyclen) and began having strong side effects- strong headaches, bad nausea that caused me to vomit, bad sore breasts (slight enlargement), and fatigue. I was told by a friend that since the side effects started so soon, it could mean I'm pregnant. I stopped the pill 2 days ago and the symptoms are still here. Has anyorne had side effects appear by the 2nd pill?
