Help!!!

In November 23 2020 I had a D&C for a missed miscarriage. I was supposed to be 12 weeks 6 days but the baby stopped growing 8 weeks 1 day. 😞 December 26-29 I had my period (very regular and normal), on January 16 at what would’ve been 7DPO I got a positive pregnancy test, well, Jan 22-25 I got a my period (regular period again). According to Glow, I was due to ovulate Feb 5. I tested yesterday and got another positive pregnancy test. I’m due to get my period Feb 18. WHAT IS HAPPENING? I need advice so I can figure out what to do. I’m so so confused and feel defeated. Could it still be leftover HCG? I don’t know UGH
