HCG Levels at 4 Weeks

I recently got a positive test back (3 days ago) and have done in total 4 tests now including that one. They all came back as faint as, or fainter than, the first one. **The ones that came back fainter were with my diluted urine**. My period is due tomorrow so I know faint lines are still good lines but there's been no line progression at all. I had a missed miscarriage in July and am really worried about this pregnancy also not developing, or having a chemical pregnancy. I'm getting my bloods drawn tomorrow, I should be exactly 4 weeks then.

What was everyone else's HCG levels at 4 weeks? Just so I have something to compare to when I get my results, as my doctors office tend to give very limited information for any and all tests my family have had there
