Ive been on btrack control for nine months. I started this months pack three days late. I doubled up until I was on track. Ive been on track for about eight to nine days I think. I am due to have my period in a week. The person I am with did use a condom a couple days ago and now I am seeing break through bleeding aand browndischarge. Im worried. Do I need to get plan B? My life is really stressful right Now and I take multi vits for my skin, low iron and for insomnia . I also have a bad cold but I'm taking over the counter meds. So.... What is up with my body, could I have gotten pregnant ?
