BFP for baby # 2

Tested on Thursday, faint positive, and again today on a digital upt and BFP again:) my only question is about the "how far along" piece. According to my period, I'm 4-5wks, but the CB digital says 1-2. Anyone with experience that can clarify off hand? Already have OB. Set up for end of the month. 
Congrats to everyone as well!
