don't feel connected to baby

I sound evil  and I know it. But with my son I saw him twice a week in ultrasounds... I never worried he wasn't okay even though I had high bp... Now after loosing one of our twins (at 9 weeks) and having a bad gender read (first it was a boy two weeks later it was def a girl) I was so upset and now at 37 weeks I haven't seen our baby since 22 weeks. I don't feel like she's really coming, it's hard to explain... Like I feel like she's not real or like she won't make  it and I can't picture her here with us. My husband has had so much loss in his life, he was a refugee from Darfur and lost most of his family to a crazy genocide :( I feel like if our baby doesn't make it it would kill him and I have talked to my doctor about it he thinks I'm crazy basically .... Not to mention I have lost over 20 lbs with this pregnancy and have been so sick :( I am 200lbs so they are not concerned about me loosing weight but I am so concerned she isn't growing  rite or somethings really wrong with her.... I guess I'm looking for support or to know I am not the only one who feels or felt like this ....
