Line progression is weird and faint

I know I’m taking way too many tests, please don’t judge me! I know hcg needs much more time to raise or double...

But I had a missed miscarriage last year and I’m paranoiac. I just wanted to see that my lines are progressing and when I see it’s fainter I go crazy and keep testing more...I know..stupid.

But on my One Step tests the lines were literally so faint yesterday all day and this FMU today... I freaked out and stated crying....

My SMU at least kind of darker again, but dont know.

Meanwhile the Clinical Guards are kind of same color in the last couple of days..

What do you think?

I’m 13/14dpo today and tiny bit cramping. I also had a bit of pink spotting this morning...:/ I’m aftaid what if it’s the start of my period.
