Incompetent Doctor

I've Been Going To An OB Since I Found Out I Was Pregnant At 6 Weeks. At All My Appointments And Ultrasounds I Was Told Everything Was Fine And My Baby Was Healthy. Well I Found Out My OB Didnt Deliver At 28Weeks And I Transferred To A Different One At The Hospital I'll Be Delivering. At My First Ultrasound At 29 Weeks With My New OB I Was Admitted To The Hospital For Two Days Because My Baby Was Too Small And My Placenta Is Insufficient. I'm 34Weeks 6 Days Today And Tomorrow Will Be The Second Week I've Been In The Hospital. It's  Very Devastating Because If My Original OB Had Told Me That Everything Wasnt Alright Then I Could Have Switched Earlier And Gotten The Medical Management That Was Needed In The First Place. Also I'm Being Monitored For Preeclampsia.
