Ladies!!! Help??

I had a miscarriage November 13th. We weren’t trying but also weren’t not trying. I had a blood test and my results showed my hcg levels have dropped back to 0. But I started to feel pregnancy symptoms again. I tested and got this!!! Is it too faint to be a positive? (This is the same test just one taken immediately after urination and one after 3 mins) thanks!

UPDATE:

I don’t think it can be hormones left over from the previous pregnancy because this is what a test looked like on the 4th
