Progression but spotting

Hey everyone. I guess I’m just looking for a bit of reassurance today. I have 2 little girls and we’re trying for a 3rd and I’ve had 2 miscarriages. Both were early 5-6 weeks and started with cramping and spotting (I didn’t have spotting with either of my heathy pregnancies). Neither test got very dark or progressed. So here we are again (4w4d) and my line is progressing (top to bottom: sun, mon, wed) so that makes me feel good but I’m having some light cramping and a very small amount of brown spotting when I wipe. Do I need to be worried about the spotting or does the line progression mean it’s probably fine?
