Line Progression

I see a lot of talk about line Progression and I’m getting scared because I don’t really see it in my tests. I’m about 13-14dpo today and I tested about 48 hrs ago. The lines don’t look darker really and I don’t know what that means 😔

I’m not gonna lie and I’m just saying it because it’s running through my mind like crazy, I’m so scared. I lost a baby in September and I was thinking this is my rainbow baby. Now I feel like I’m losing another one. My symptoms are still strong and I don’t have any bleeding but this is really taking a toll on me when I see other line progressions and I don’t have it.

Please tell me what you think!
