BFP 4 weeks post D&C

I had a D&C; on May 22 due to a blighted ovum discovered at 9.5 weeks. The doctor didn't follow my hcg levels afterward but was confident he got everything. I'm going to retest periodically but just wondering if this looks like a new positive or residual hcg. From my Google and Glow searches most I've seen are much fainter. Any help? This was this evening
