My first pregnancy was a miscarriage at 12 weeks (no bleeding only knew that something was wrong by ultrasound - the baby did not have a heartbeat and went for a D&C that same afternoon) Was horrible. My second pregnancy was my beautiful son, born 18th January 2004.
Miscarriages are so tragic, but also so very common. Statistics show that around 1 in 4-5 pregnancies end in miscarriage. There are many reasons behind them, some reasons being that the egg did not fertilise properly or that something just did not develop as it should, and natures way is to terminate.
I was soooooo nervous during my second pregnancy, I kept telling myself that "When I see his heartbeat at my 6 week scan I will be ok" Then it was "My 12 week scan" then "21 weeks and I will not be nervous" that continued on and on until I gave birth to my gorgeous little boy at nearly 41.5 weeks!!!
Best of luck
