Line progression

Hi everyone, this is my rainbow pregnancy after almost 10 months. I got my bfp last Monday exactly a week ago on 12dpo and I have been testing since then. I know I shouldn’t bc this will just lead to anxiety but it already has...so my concern is the last 2 tests look exactly the same, I thought my test today would be darker but it is not. Also every single day the last 4-5 days I’ve been getting this adrenaline rush type of feeling in my breasts (which happened last time I was pregnant too) but from today that is suddenly gone. I had it so bad all day yesterday which is why I’m freaking out. What do you guys think? Am I worrying for no reason? Planning to ask my doc if I can do more hcg bloodwork
