Heartbroken

Michelle • I`m 24 baby Declan arrived 08/07/2017! I have 3 angel babies.06/18/15 and mono-mono twins on 06/27/16.
I went when I as suppose to be alittle over 10 weeks to an ultrasound that I paid for it showed I was only 8 week 2 days but still had a heartbeat scared I called my ob and could only talk to the person at the front desk she told me I had an appointment on the 22nd and to just bring those in then to compare. I had just meet with my ob the week before and she did an ultrasound and said everything was fine and she saw the heart beat. So I waited I had brown spotting off and on since I found out. Then Friday morning around 4am at work I had light pink spotting that turned brown around 9am still worried I called my ob again I talked to someone at the front desk said everything was fine I had an ultrasound the 22nd call back if it got worse. I didnt go to work that night around 3am Saturday morning I had some red spotting worried I called the on call ob took them 2 hrs to call me back I finally feel back to sleep before then. I listen to my voice mail sad to call back if I had anymore concerns. Monday morning I was having yellow discharge and I called and I finally talked to someone else and they made me an appointment that day to see my ob. They asked me why I was there my appointment was next week my ob finally came back and said she was going to try to get me in for an ultrasound earlier she got me in the same day I made a new appointment with her for a month since I had another one the 30 of June that I didn't need since she just saw me. I walked my way down the hall to the ultrasound texted my so that I was getting ultrasound and my next appointment was moved. I waited about an 1hr finally I got to go back. As soon as she put the ultrasound on my belly I knew something was wrong my baby looked the same maybe a little smaller. I asked her I'm not measuring right she said hold on she want done yet. At the end she said your only measuring 8 weeks 2 days. I asked what was the heart beat... there wasn't one. I broke down I was by my self thinking everything was fine but deep down I knew it wasn't all along. They made me go home told me to come back the next day at 8:30. I came in they gave me my options my so and mom was by my side. My mom was sure they were wrong and had me do another ultrasound which made it worse I knew it was gone. I start crying and the ultrasound tech told me I need to clam down she couldn't get a good view. Now I'm waiting for my medications they couldn't get them in yesterday and they told me if I wanted a D&C I had to wait up to 2 weeks I could wait another two weeks knowing I carried it for three weeks and it was gone. 
The worse thing for me is that I knew for two weeks something was wrong and they wouldn't let me come in when I had that ultrasound. The other thing is that I measured only 8 week 4 days when my ob did the ultrasound and didn't tell me about it she knew I wasn't measuring right and didn't tell me.
I called about every week with problems and no one took me seriously. If they would maybe I wouldn't have carried my baby with no heart beat for three weeks.
