I delivered a stillborn at 32w2d, it will be a year ago in 6 days. There was no cause of death found after having an autopsy done. We have waited to TTC again till just now. We have waited b/c my DH wanted to wait. I would wait for an autopsy report to come back first to see if they know what happened so you can know if there is anything to do to prevent it next time. I had a c-section and was told I needed to wait 3 months before trying again. I'm sure all doctors have different opinions about that though. Good luck to you when you try again.
Btw, I'm so sorry for your loss, I know how hard it is. If you ever want to talk, feel free. I'm not here often, I pop in once in a blue moon. You can find me at my blog though.
