Positive tests but possible chemical

Hi,

I had a chemical last month (baby number 2, 14 months of ttc). I had a strong positive at 12dpo and 13 dpo and a positive digital at 14dpo, however 4 days later tests showed negative and I had a chemical the next day.

I caught again this month and had a faint but there positive at 12dpo with an afternoon urine, tested with FMU today as AF would be due today and the line is there but no darker. Should I prepare myself for another chemical as it’s not darker? With my first baby i tested negative until I was 5 days late so none of my pregnancy testing has been consistent! I’m so confused and so worried! Has anyone had the same and it’s gone on to be ok? I’m so shocked after ttc for so long and then catching 2 months running!

(Top test is 12dpo PM urine and bottom is 14dpo FMU)
