Freaking out

I had two very positive FRERs on Sunday and one very very positive test yesterday. 15 dpo. Went to my doctor for their confirmation test (urine) and it was stark white negative. They ordered a quantitative hcg blood test and I’m anxiously waiting the results. Even if I was losing this baby, the line was SUPER dark just yesterday, wouldn’t it take time for the hcg to go down?

Someone please share some reassuring news.
