Faint FRER lines

Kailie

Today, 11/8, I am 13dpo. Should I be concerned by the lack of progression between 12 and 13 dpo? This is my first cycle TTC since I had an early miscarriage at a little over 6 weeks and my lines were stagnant and slow to progress during that. Granted that cycle I didn’t get a faint line positive until 14/15 dpo but I’m feeling very anxious. I am going for blood work tomorrow but I’m afraid the HCG isn’t high enough to get a good number based on these lines. Looking for similar stories or advice that leans toward this having a good outcome. The screenshot is the first response app and it reads the test as positive. I think I see the faintest line in a clear blue pink dye test and digitals are negative.
