Are my lines progressing enough?

cami

I’m 10 dpo today. I got my first positive yesterday. I took another frer this morning and it looks the same as last night?? I know that hCG is supposed to do every 40 hours. I feel like you should’ve gotten the darker line by this morning since yesterday‘s jump was so big?

1st test 9 dpo am

2nd test 9 dpo PM at 7

3rd test 10 dpo am at 5 am
