can anyone help

Breanna • 25 married to my high school sweetheart with one beautiful daughter.
I'm three to five weeks pregnant ,were no quite sure yet, I randomly get light brown spotting. I'm super nervous with this pregnancy it's my first one. I get cramps on and off and spotting once in a while. I'm going to talk to my docotor about it but until I see her can anyone help ease my mind? Please
