Hi pinkyrose, thanks! Yah was surprised to find out the gender so early but actually, already had a feeling it was a boy cos my nose was getting rounder by the day

Plus this Chinese physician (whom I saw in early days of pregnancy and who felt my pulse) plus facialist (who probably deduced from my awful dry skin) had also told me they thought I was having a boy. Funny how all these old wives tales came true in my case! I haven't tried the ring test yet though.
Re oscar test, I think no harm going for it regardless of age as it will give you peace of mind that baby's ok. Even if you won't terminate if (TOUCHWOOD) really DS, at least you will be mentally/ emotionally prepared before the baby comes and can make special arrangements re childcare etc? But it's a personal choice so up to you!
If you really don't want, maybe an alternative is to ask the doctor during your next scan if he can see if the baby has a thick neck and whether the nose bridge looks ok enough. Not a guarantee that it'll be ok, but usually if no thick neck apparently it should be ok. My doc had already indicated even before my oscar test that she thought the baby should be fine, based on what she could see from the scan.
Re headaches: I get these on and off though not as bad as yours. Supposed to be a side effect of pregnancy, unfortunately. Hang in there!
Btw re strollers: have been advised that it's good to buy the kind where the baby faces the mother (and not outside). Supposed to build confidence for the baby and also you can continue to talk to and stimulate him as you push the pram. But I also would like my baby to see the outside world sometimes so trying to look for those strollers that can go both ways.
