S.K.
First of all, I'm so sorry to hear about your loss of your baby. I was actually surprised at how strong my emotions were when I first miscarried. I knew it was a loss but didn't expect it to be so intense.
I have had 3 miscarriages, all before my two boys were born, but the first one I was nearly 13 weeks. We had seen the baby kicking around and moving on the ultrasound so they assured us the risk of losing the baby at that point was very little. Still statistics don't matter if you're on the wrong end of them;).
One thing that surprised me was that because you're further along, your hormones may take a similar journey to return to normal as they would after the birth of a child, but with the loss your feelings of loss and sadness may be amplified. I went to see my doctor because I was having such a difficult time moving on and finding peace.
I know everything tells you this, but know it was nothing you did to cause the miscarriage. Most of the time, there is something else going on your body or the baby's.
A Place to remember ( http://aplacetoremember.com/ ) has some good resources and some nice remembrances for babies lost to miscarriage, stillborn or shortly after birth. It really helped us to have a little naming service just my husband and I and we gave our baby a name and dedicated him/her like we would have if we had been able to baptize the baby. Some people really appreciate these steps and some do other things but finding some way to acknowledge our baby was important for us. We also have angels for our christmas tree for each baby we lost. They are just plain angels, but they are important to us.
I did go on to have two healthy boys and am pregnant - about 15 weeks - with our next child. I feared at one point I would never have any and I can't say I am totally relieved until I hold my baby, but know lots of us will be praying for you.
God bless!
