Feeling helpless and worried

Laura • Mom of 1
We got a bfp a week ago. I'm going in to see my doc and ask for blood work. I've have very faint brown tint to my cm for 7 days now and it's scaring the shit out of me.  Also my breast pain isn't very strong like it was last time.  Every cramp is so scary. I just want to know things are progressing alright.
