Terrified Its a Chemical

JBo
Im so terrified that our little bean isnt  sticking.  I had dark brown discharge for a couple days which makes sense as implantation bleeding but this morning had slightly brighter blood.  I will be devestated if this is my period.  I took a hpt today and it was slightly darker than yesterday's but I know that doesnt necessarily mean much. I reached out to my RE to see if they want me to take beta today or wait till AF was due which is Wednesday 4/12.  Not sure I can keep it together two more days.  Please keep us in your thoughts amd babydust to everyone.  Im 12 DPO today and 13 DPIUI
