So sorry to read of more loss on this thread
If those of you who have had losses from this thread wanted to join, we have a July 19'ers thread on Conception board. Some of us will be TTC straight away but some of us are waiting. It's a thread to process what's happening with our loss and grief rather than just TTC. 
As for symptoms, I don't think you can go by them too much. Half off the people who have had a loss on here appear to have had no symptoms but others still have symptoms (like me, still being sick everyone morning and lactating but I've a confined MC)
