Babar's TTC after m/c Wish

So far, my husband and I have had no luck being pregnant...one m/c one d&e after being 4 1/2 months along...she just stopped growing. Now, we are trying again, well, not preventing is more like it. There are tests I can take to see if there is something wrong with me, to see if there was a reason I have had such bad luck, but I don't think there is anything wrong. Things just happen sometimes, so I am leaving it in the hands of a higher power.
