here's our experience (caveat that katie was pregnant, so she'll probably add something different than me later):
we had two very early miscarriages last year: one on new year's eve and one on our ds's bd. lovely. the first was quite painful to go through, mostly because we had really begun to plan out life with the idea that we'd have a new babe in september, a new babe with us this past most recent christmas, etc. it's so so hard to realign your brain once you've set it all up with expectations, excitement, etc.
both mcs happened naturally. we wanted to get right back on the ttc bandwagon, but were advised to wait a cycle. i'm glad we did, because the post-mc cycle each time was SUPER long and even crazier than katie's normally crazy cycles. her first period after was also slightly heavier than normal.
the 2nd mc happened the next cycle we were able to try after the first. we reserved super high hopes and dealt with that one very differently. we did see the doc, though, to figure out if anything was going on. katie got a sonohystogram to be sure everything was ok in her uterus. it was important for us to do that to check things out and be sure there wasn't anything physical causing things. the doc said he only worries after 3 mcs. not super comforting, but sort of.
the next time we were able to try, we didn't get preg at all. which was sort of a relieving change -- to know it just didn't happen that cycle. phew! same the next time. super hard to wait, but no sadness or loss.
i think, if i had been able, i would have allowed a bit more time for grief around the first mc as opposed to hoping right away to jump into trying again. but that is so hard as waiting is the hardest thing about this whole ttc process. not sure what else....the second one really helped us to cherish the son we do have and to enjoy him in a different way, which was actually nice.
hugs and healing,
