I have this paranoia that mine line is getting lighter. I had MC in May and that’s how I knew I was having miscarriage so maybe it’s just my fear but I need your help ladies!

This test was taken 14 DPO on the day my AF was supposed to show.

These were taken today in the AM 15dpo one day late. I feel like the blue one is lighter although it was with the same urine. I’m so scared I’m thinking of going today and 17th to give blood test to see if my HCG has doubled. I’m terrified coz last time I did that it went from 48 to 27 :( but my line last time was nowhere near this dark. Any opinions? Or am I just paranoid?
