brown spotting/darker test line

Lillu

I’ve been having light brown spotting the last couple days, but tested again today & the test line is so much darker than 2 days ago..am I freaking out for nothing? Anyone else have light brown spotting in early pregnancy & what was the outcome? No cramps or red blood, but I’m also not feeling many symptoms. I’m 6 wks - mc’ed once before but we’ve been trying now for 6 years. Praying this baby is healthy & growing🤞🏻
