Question about chemical pregnancy

When are you past the possibility of a chemical pregnancy? Will your line every be dark on a hpt?? A picture of my tests are below 10dpo-13dpo (I know it takes 48-72 hours for hcg to double/rise, but I couldn’t help myself... I also know that you should test at the same time when you do test... like I said, I couldn’t help myself). I had a chemical last month but didn’t fully understand much about chemical pregnancies. Are my tests looking ok so far?? I know it’s early and AF was/is scheduled to show up tomorrow. Any input is greatly appreciated!! Thanks ladies!
