Butterfly, what a beautiful post. You are obviously a special soul and that is such a lovely way of looking at things, made extra special by how hard the situation is.
Wish, you are not over reacting at all! Yes, people miscarry all the time, just like people get pregnant all the time. Any miscarriage is a sad loss of life but the physical, emotional and financial toll that ivf cycles have I think makes it seem more cruel. Plus, this is happening to you, not someone else, and you have every right to be upset and grieve.
I know I will worry for the entire duration of this pregnancy and won't really be happy until bub is safely here. I'm already driving myself crazy worrying about my 12 week scan, I'm so scared something will be wrong. I reflect everyday on what a precious miracle my son is and am thankful for him every day. I hope and pray everyone here joins the miracle mums group very soon.
