16 dpo, does my FRER look good?!

I miscarried twice since July and I'm sooo anxious this time! 
With my viable pregnancies my first response early result tests were very dark by 16 dpo. I was supposed to start today. Also they don't seem to be getting darker very fast.  
What to yall think...top one is yesterday morning and bottom one is this afternoon. 
Thanks for opinions, I'm just really scared. And I'm spotting and cramping on and off.
