Light brown spotting normal at 5 wks 1 day?

It’s very light, I can post a picture below but it never fills a pantyliner. I tested last night to ease my mind since I’ve had back pain, cramps, and the spotting. Here’s last nights test below. I go to my first appointment on Monday I’ll be 5 wks 4 days.

Below here is a picture of my very first test on the 29th of Oct.

So the line has gotten darker from this last picture from yesterday’s but I just want to hear personal experiences from you mamas.
