Can this be positive already?

Okay so I did my second round of clomid this past month. Period December 18th 2018, positive opk on December 31st, Jan 1 and Jan 2. Glow says I ovulated on the 2nd but I’m thinking it’s wrong. Because last night I took a LH test and HCG (pictured bottom) I swore I saw a shadow on the HCG but was shocked to see the LH so dark. So I tested this morning. (6dpo according to Glow) and it’s a clear positive!!

I can’t imagine this is normal. I have 2 kids and neither tested positive before 10 dpo.

Thoughts?
