Poas obsessed and nervous

Br

I have taken a test literally everyday since my first positive at 10dpo. I’m obsessing over the line getting darker and worried about a miscarriage or even an eptopic. I have 3 friends that had a miscarriage in the last year so it has me nervous. I wanted it to be a really dark line by now so I could call my doctor. Are these lines getting darker enough at the right times? It goes 11, 13, last was today at 15 dpo. Between 13,15 is where I don’t think it got dark enough to be two days.
