High HCG?

Okay so I might just be over thinking cus I'm in shock but I tested at 10dpo & got a dark positive (4 days before my missed period). Then again this morning at 12dpo (2 days before missed period). I thought they would've been faint positives. Didn't expect them so dark. So anyways it could be because I have high HCG levels right?? The first picture in person it looks darker & in this pic the line looks lighter.
