I spoke to her again (she lives in Nth QLD & I'm in NSW, bit of a pity actually because I don't think those around her are very supportive) & she said that she went & saw another GP who drew bloods (as the first thought it was a waste of time, his exact words!) I think she gets the results of the HGC levels today. But she has nothing to compare them too yet as this is the first lot done. Hopefully they are nice & high though.
She didn't mention it being an internal U/S so I assume it wasn't.
She has also had 2 m/c in the past & apparently has a stunted uterus or something. Its one of those things that every says she has but no one actually has a proper name or diagnosis of her "condition" I suspect that it was a passing comment made at one of her earlier m/c & wasn't actually followed up with any real diagnosis KWIM?
She has carried to term two kids. This will be a much wanted #3. She has been trying for about 12 months I think but she has very irregular cycles & her DH works 2 weeks out of 3 away from home so catching the unpredictable egg is difficult.

She has said she still feels as though she is pg as she is sick & her kids are pushing all her buttons, she tired etc. It all sounds positive to me. But those around her (parents, older sister) are just kind of ignoring. But thats what they are all like. Turn a blind eye to the problem & it magically disappears

I will let you all know how things go.
