Backstory: On February 14, 2017 I had an intrauterine fetal demise due to a congenital heart defect. Delivered the fetus naturally at 18 weeks, bled for about a week, no further issues. Doc said no need to wait to try again as they were confident it was a spontaneous defect. On March 20, I started what I think was my period except that the blood was brighter red than usual and didn't contain any clots. Contributed this to the fact that my lining had been shed with baby and hadn't built up much again. DTD several times throughout the last week of March. On April 7, I experienced what I believed to be implantation bleeding (same as with first pregnancy) and for the following week (week three, technically) I experienced mild cramping. Since, I've had consistent cervical mucus, sore breasts, etc.. Now 5 days late, faint positives on some tests, negative on others. I feel like I'm losing my mind!! Could I have gotten pregnant so soon? Is it a bad sign if the line is not getting any darker over the last week? Help!
