Is it possibly my levels haven’t gone down?

I had a miscarriage on May 16th. I stopped bleeding within a week. Ovulation and period came back quickly and I’ve been very regular since. June 19th I took a HPT and swore I saw a line but then got my period. It’s been a while cycle, so I took another HPT today (should be 11DPO) and again swore I saw a faint line! Now this one looks more promising than last month. But is it possible I have leftover HCG in me? Surely not since I’ve had 2 cycles since my miscarriage...I think I just have baaaad line eyes lol
