Dye stealer?

Hi! I posted in another group via Glow when I got a faint positive test a couple of weeks ago. I found out I was pregnant 6 days before my missed period. I just took a test today to monitor my hormone levels because it gives me peace of mind until I go to get my first ultrasound in a few weeks. I am 5 weeks 3 days. Would you say this is a dye stealer (possible sign of twins) since the test line is way darker than the control line? Or is it just that way because I’m very pregnant now and my hormones have risen?
