4 weeks after miscarriage

My baby stopped growing at 6 weeks and I started having a natural miscarriage 4 weeks ago. I've been having period like symptoms so I tested to see and this is what I found. The top was yesterday and the bottom was this morning. Does it look like it can be residual or is this really my bfp rainbow?
