Has anyone experienced this?!

I had my miscarriage on 1/18. My hcg has been dropping pretty consistently since. Last Thursday it was at 10 and my home pregnancy tests were negative. Saturday I took another home test and it was negative along with (finally) a negative ovulation test. Well today I took another hcg test and an ovulation test and the ovulation test is raging positive alone with a faint line now on the pregnancy test! Can hcg just pop back up like that? Like is it possible it’s leftover hcg or could I be pregnant? I had an ultrasound when I miscarried and everything had passed.
