I'm really annoyed with my doctors office. My obgyn was supposed to send my referral for my anatomy scan at my 16 week appointment so that way they could schedule me for my anatomy scan between the 18-20 week mark. I went to my obgyn at 18 weeks because I thought I might be getting a bladder infection. They checked luckily all good. My ob asked me if the anatomy scan place had called me yet to set up an appointment. I told her no I hadn't gotten a call from them. She told me if they didn't call in the next week or two to call them and let them know so they can make sure they call me. Well I decided to call the anatomy scan place the next day and come to find put my doctor never sent the referral to them in the first place and I needed to call them and have them send one. I call them and they transfer me to my ob's nurses station and was told to leave a message if they didn't answer and they would get back to me soon. A week later I call the anatomy scan place they checked all their faxes and pending referrals and nothing from my doctor again and got told to call them. I call them same thing transferred to the nurses station, no answer I left a message again explaining the situation and asked that they please call me back asap to let me know if it was sent. Never got a call back. I will be 19 weeks tomorrow and I doubt I will get a call back. Will they still give me an anatomy scan after 20 weeks?
