I've had 3 miscarriages in the last three years. 2 of them within the last 5 months. I am now pregnant again with the 4th and was told by the measurements of my GS that I would be 4w5d. On my 2nd U/S they seen the sac ad yolk sac but I was told my hormones were very high to where I should've seen more. Anybody else experience this? I go again Thursday for more hormone tests and Friday for another U/S. I've researched and seen a few stories about blighted ovums and carrying twins.
