Lines aren't getting darker..updated

Willow

I've had 5 miscarriages in the last 2 years and my lines aren't getting any darker than they were 4 days ago when i got my first fl and positive digital.. I have an appointment Monday morning but has anyone else experienced this and it ended up perfectly fine? I've been cramping a lot and it's made me very anxious even though I've read it's mostly normal with a repeat pregnancy.. Update: miscarriage #6... I'm so tired of not knowing whats wrong with me.
