Okay so I told myself I wouldn't post on here until Monday when we see the specialist, BUT I am so worried, or at least worried about whether or not I should be worried

That I thought I would now. . .
At our 20 week scan they took AGES looking at the heart, she had to call someone else in, and she also took ages, but in the end we got an 'I am fine with it, looks fine'
We had to have another scan the other day, to check the placenta had moved (which it did) but because of last time we always had it in the back of our minds so we asked her to check again.
Turns out she said 'lucky you got me to check' because she coudn't see the right ventricle or if she could it was really really tiny, her exact words were. "it's really small, if thats even it at all" also the right atrium was mildy dialted.
Is it even slightly normal not to get a good view of this???
SOOOO we have an appointment on Monday, but we are finding the wait HORRIBLE.
Has anyone else had anything at all similiar? Even had to have a heart echo in the first place?? Was it anything?
I have heard about 20000000 stories in the last few days about babies born with heart problems that have been fine, so I am not TOO worried about 'it will be okay' I know surgeons are legends these days if it comes to it.
I really just want to know if anyone has been sent for an echo and there was actually nothing wrong at all, or if anyone has had something similiar happen to them. . . . . . I feel like I am doing 'something' by asking questions here instead of just driving myself crazy waiting!!!!
. . . See that was great, that just cut out a full half an hour of waiting out of my day writing that!!!
