Thankyou everyone for your comments this week. I've had some good news and it seems everything is ok.
You know there is a problem when the obstetrician rings you on a Sunday night as soon as he gets your referral. Apparently my GP had looked at my 12 week ultrasound report and seen there was a low risk of Down's Syndrome and I was told everything was fine. What they didn't tell me was that there was a really high risk of a few other chromosome disorders, ones which have quite severe consequences. No one should have to be told this at 17 weeks and then be told it will take a few weeks to get the results. So I was booked in for an amniocentesis as soon as I could get there. Luckily I was then told there was a very quick test they could do and I would have fairly reliable results in a few days and those results were good.
So I am feeling so relieved and very drained, but I just had a good nights sleep and the world looks a little brighter again. I am still pissed off (to put it mildly) with my GP, but I don't want it to fester and I'm pretty sure he will never make that mistake again.
I really enjoyed just hibernating at home and doing some sewing, I think I might do a bit more of it.
