Can someone help me figure this out??

I'm so confused, I had a D&C; for a missed miscarriage June 1st. I had foot surgery done about 2 weeks ago where they did a urine pregnancy test that came back negative. Then last Wednesday, July 5, I got a positive hpt. That Friday I had blood work done as Dr has been tracking hcg, (still waiting on results, the previous blood test had them at 15 two weeks prior)

Today I started bleeding, tested and second line is still there but much lighter, has anyone been through this??
