mama sorry to hear your news. Hope you have lots of support whatever the outcome.
angel I'm 32 and my obstetrician told me to expect a risk in the region of 1:2500. She said with the age factor, you'd have to have exceptionally good bloods and a great nuchal measurement to get much lower. Age alone risk for a 32 year old is something like 1:475, so it's still substantially reduced compared with that.
tea I have two jobs. I told one place at 7weeks, because they offered me extra sessions, and I just felt it would be wrong to take on a whole load of new patients with 2year treatment plans only to go off on mat leave after a few months. I don't think I'd want to do as many hours as they were offering when I go back either. I told the other place at 10weeks because the practice is up for sale and the guy that is hoping to buy wanted to know whether or not I wanted to stay on post sale. If it hadn't been for those circumstances I wouldn't have said anything until after 12 weeks. I think if something goes wrong from this point onwards I'd be wanting to take a reasonable amount of time off anyway, so I'd have to tell them anyway.
As for exercise, I played netball till 20wks with DS, the only reason I'm not doing that this time is because the season's finished. I still do what started out as a post natal fitness class, but is now really just a boot camp for mums. They can just modify stuff for me as I get more pg. One of the other ladies is 35 weeks and she ran 5km with us last week 
I doubt I'll be doing that!
I've had several comments this week that I'm getting a proper bump. Didn't show at all with DS until about 20weeks, so it must be true that things never quite go back to where they came from.
