LH levels keep rising

Hay I’m at 8/7 dpo I think I completely left testing my surge for this month but I know I ovulated on the 19 as everytime the app is correct but this time round LH level keeps going up slowly slowly and I’m getting worried thinking if it’s a sign of somthing negative as I’ve never had this happen before I need someone to help me here please

LH level reading is 0.57

And also according to google and other search it said implantation would happen on the 27th which was yesterday.
