Inconculsive Doctors Urine Pregnancy Test

I have had 6 positive pregnancy tests before I went yesterday to confirm my pregnancy. I got a call today saying the urine test was inconculsive for positive or negative. They asked me to go in for a blood test today. Afterwards I was nervous so I went out and bought more pregnancy tests and they are even darker than before. Has this ever happened to anyone? The nurse said the labs testing isnt as sensitive as HPT so if its early it may come back inconculsive. The nurse said she will call me tomorrow with the results. I am pretty positive they will be positive!

The bottom test is from 6 days ago when I first found out and the one on the top is from after my blood draw today!

The first two are from after my blood draw today and the last one is from 3 days ago. I have also done numerous cheapie tests too that were positive.
