Same 🤔🤔

I took opks yesterday afternoon and last night

⬇️below pic is from yesterday

They have been the same color sun ve the 3rd. (Yes they are all negatives I know.) I'm on metformin and I just started it this Wednesday.

EDIT: Just took one not even 6 minutes ago.

It has lighten up alot!! Is this normal for it to be that dark of a negative to being rmuch lighter now
