Hey, so ive recently found out im pregnant, but my tests are all coming back as faint positives, various brands ive used pink and blue dye, all came back faint positive withinin the time frames, but they are not getting any darker, and im 4 weeks 6days, so im worried that something is wrong. I already have children, but also have had 5 miscarriages in the past with the recent one being back in march...anyone had this and had a successful pregnancy.
