I had a lost at 16 weeks 4 weeks ago I had a feeling I was pregnant I tested and it was really faint then the next day it was negative and tested today it's darker. I was nauseas today so I took it but I'm having light bleeding now like a period, when I checked my pad it was dark brown. I don't have cramps but I'm scared I'm having a miscarriage :( . Any advice , could I be fine or at high risk ? Has anyone experienced anything like this.
