I'm so sorry for your loss. You have the right to morn the passing of your baby and time will make things easier. Many of us have had a m/c at some time in our life so we can understand what you are going through. I know for sometime after my loss I was resenting everone who fell PG, there have been at least 6 ppl. That was untill one of my collegues had a loss at 18 weeks. I then realised how lucky I had been, dispite my loss. I don't know how I would have coped in her shoes.
Oneday, when the time is right, it will happen again for you. You must heal from this hurt first though. I have dealt with it by making my angel baby my gardian angel. I don't know if it was a he or a she, but I know they are watching over me.
As hard as it might be, you must push on, make a good stable life for the children you will have oneday, it will happen. Take care.
