TTC & Drs

going to my OBGYN for a follow up in a month or so because tomorrow is my son's 1st birthday! i want to tell him that my fiance and i want to start TTC in a few months but I'm nervous about what he might say? we are young BUT we have our own place and dont ask anyone for help or even need if. We are stable enough financially. im even lucky enough to be a SAHM. ive told a few close friends and their reactions have me second guessing. did your OB have anyrhing negative to say about having another?
