I had a slight bleed yesterday but when I did a test it was still dark, I did one this morning to see if it was still dark and it's very faint. I'm so worried and confused the bleed was only slight not like last time (which was 5 days) but the test being faint makes me worry. A friend said it could be implantation but I ovulated on 8/3/17 so technically I should be 5 weeks 6 days is it not to late to be implanting? So confused and upset
