Miscarriage and Stillbirth

After 3 1/2 Years of trying to concieve we finally found out we were pregnant June 17, 2006. We were excited, we immediately started buying baby stuff and I was resting as much as I could. I ate healthier and avoided soda's. July 28, 2006 my husband woke me up to see the sunset. After watching the sunset for 10 minutes I went into the bathroom to do my usual routine. I then found I was spotting some blood. I was scared so I asked my husband to take me to St. Marks Hospital. When I got there the doctor immediately did an ultra sound to find an empty sac. I was disappointed, I cried all the way back to the room. Then a priest came in and asked if he can help us with our loss. We were not told yet that I was going to miscarry and that we had lost our baby some time ago. My husband and I told the priest no thank you and sent him on his way. The doctor came and told me that we were going to miscarry.
The doctors did not explain what had happened and my husband and I prayed all weekend that a miracle would happen and that our baby would be there on Monday when I was going to have another ultra sound if I did not miscarry. By Sunday night I finally came to the conclusion that I was and started to bleed heavily. By Tuesday I had not passed any tissue and went into labor-like contractions for 13 hrs. Finally the doctor decided to do the D&C.
My heart is broken... I find it hard to get up for work. A lady at work has a daughter who is pregnant and ready to have her baby. Her daughter is not married and tells how easy it is to get pregnant. I have to go to the bathroom to cry every time she comes in or the lady discusses the progress of her daughter's pregnancy. I feel frustrated with our Heavenly Father. Why did he do this to me. Why wait 3 1/2 years to lose my baby?
