TTC after chemical pregnancy

Hi! So I had a chemical pregnancy last month. (8/19). I had blood drawn until my hcg levels were down to zero. I never got my period, but today, I got two BFP. Just wondering if anyone else got pregnant right away without having a period. I know my levels were down to zero, but I’m still paranoid that this is from possible remaining hormones from last month.

Side note: we did not have unprotected sex until about a week after the chemical. I also DID ovulate based on an opk test...

Thank you!
