TBH I don't know. It has taken me months & each time I had another m/c, I felt I was right back at the start. I still had to keep going to work, tending to my DD etc...- I couldn't put these things on hold but that didn't mean that I wasn't sad, upset etc.... I just kept it suppressed until I was in an appropriate environment (ie: not work) where I could cry, trawl sites like BB for support, took baths, had a facial to make me feel better - whatever to make me feel better. I too focussed on trying to have another baby (particularly the first two m/c). Some days are better than others, but I think that is all just part of the grieving and moving through the emotions process.
Just keep crying, venting , talking about it & it will get better.
