My period was due 7/7/17 and did not come. I just took a test and got what I believe is a faint positive I should be 4 weeks 5 days. My concern is this seems lighter than the previous time and I have no symptoms but occasional heart burn. I had a little bit of nausea but that has subside. Has anyone had a faint positive and barely any symptoms and had a successful pregnancy? Because of 2 previous miscarriages I'm a bit nervous. I took a hpt with the second pregnancy and that line was darker than this though I feel I may have been a few days further along.
