I am currently pregnant with #4. My first 3 pregnancies were through IVF so it was virtually impossible not to tell as family knew I was going through IVF, as did most of our close friends.
With this pregnancy it was a miracle. I told everyone. I was so over the moon about finally conceiving naturally after 8 years of IVF I couldn't keep it to myself. I am nearly 12 weeks and pretty much the entire world knows. I know I could still lose the baby but if I do also know I'll be supported by so many wonderful friends and family. I'd rather that than go through it alone.
