What could this mean?

I just found out I'm pregnant and I took the clear blue digital that estimates your weeks and it said 1-2 meaning 1-2 weeks past ovulation. I looked at my calendar and I should have ovulated the last week to week and half of May bc I had spotting (implantation) on June 7th. That doesn't seem to be adding up, does it? Could this mean my levels are low and I may misscary or already have? Any advice would be helpful!
