New pregnancy or leftover hormones

So I miscarried on the 23rd-24th of June and my bleeding went on until the 28th. I had been taking pregnancy tests just to get an idea of where my hcg was. My tests were negative on July 3rd so I started using OPKs that same night. The one from that night was negative. The next day, I got a positive OPK (July 4th). This morning, at 7DPO, I took a pregnancy test bc I’ve been getting a lot of the same symptoms I had before. I figured it’d negative bc it’s too early but I’m getting positives. I got a positive Walmart cheapie and a positive First Response digital. Since digitals usually take longer and need more hcg, should I take it as hormones from my miscarriage? I have my follow up appointment Wednesday (I was supposed to have it sooner, but there was issues with insurance)
