Thanks for your replies. My claim has moved to the "Gathering Evidence" stage and a "Development letter was sent" in the updates column. I'm guessing it's just a letter stating they are working on my claim or to ask for a stressor letter. I've heard it will stay at this stage the longest.
My VSO was quick to submit the FDC to preserve the date, so I'm hoping they schedule me for a VA exam before my C and P exam or maybe the C and P examiner can diagnose or confirm the diagnosis. Either way, I should have a PTSD diagnosis in my file before long from my visit to the Mental Health clinic. Walking in those doors was the hardest things I've done in my life.
