I took a pregnancy test today and had a faint line. I'm excited that I'm pregnant, but I'm worried about whether a faint line means anything. Yesterday was supposed to be the first day of my period. Should I be concerned that my levels are so low that they barely register on a HPT? My miscarriage a few months ago has made me a little nervous. Please share your stories of your pregnancy that started with a faint line. Would love to hear about it-good or bad.
