I am so very sorry for your loss. I know the pain and it is unspeakable. I miscarried a few weeks ago. I went to the OB for a routine visit and discovered that there was no heartbeat. My DH and I were devastated, particularly since we had an ultrasound a few weeks earlier and all was fine. There is no rhyme or reason for these things. We have really drawn strength from our faith and we know we have a special angel watching over us.
Please take care of yourself and allow yourself to grieve. Pregnancy loss is very isolating because as a society we do not have rituals to honor the percious life that was lost. Unless you have experienced this loss, you have no sense of the deep and real pain it causes. I've had family and friends say some really odd things to me but I realize they just don't know what to say. I have also connected with women who have had miscarriages and they have truly been wonderful. Someday a woman will share her story of loss with you and you will be able to tell her I know how you feel and that will be your gift to her. We experience everything for a reason and we are stronger because of it.
Lots of hugs and prayers for you.....
