Made fun of

So Wednesday night I went into the hospital for really bad back/abdominal pain and I was also bleeding. My baby's father too me, we're not together. He didn't want to be there what so ever because he had plan that night. While at the hospital I got an ultrasound done. I started to tear up and cry silently because I didn't see a heartbeat. I'm laying down scared to death that I might have just gone through another miscarriage. And my baby's father just decides to start laughing and make fun of. He knows everything I've been through with the miscarriages because he was the father of those too. I don't understand why he would make fun of me even after telling him why I was crying. My doctor told me everything was fine and that the heartbeat was completely normal. I just couldn't see it in the angle I was in.
