I am so sorry for your loss. My DH and I had also been TTC for over a year when I got pregnant....I know how hard it is to try for that long and then have a loss.
Since your loss was fairly early, I would think you could start trying as soon as you are ready. I have a friend who had a loss at 6 weeks and got pregnant with her son just a couple of weeks later, so you never know. My loss was at just shy of 5 weeks and we started TTC right away again, but my first cycle was kind of messed up and I ended up with just a 9 day luteal phase, so things can be a bit "off" for awhile. But I figured it was worth a shot.
