leelteloo it sounds a bit like you may have a pregnancy/hormone related migraine. I had them quite badly with my first pregnancy, and found they coincided with hormonal changes, like implantation, and at the end of my first trimester when the placenta took over more of the hormone production. Might be worth seeing your GP, specially as it's been 5 days, although all they can give is paracetamol, and sometimes codeine if its really bad. I find that using a menthol headache stick, like 4head, across the painful bits on my forehead really helped sooth the pain. And try to get as much sleep/rest as possible.
Finally, I'm starting to feel more like me again, feel like I'm coming out of the worst of that 1st trimester fugginess and I'm able to cope better. Still waiting for my skin to improve, my nails to strengthen, and my hair to stop falling out!!
Re nuchal scan result timings, I guess it depends on how quickly the hospital can process the bloods and get results. Mine did it within 30 minutes, although I guess others might have a backlog of a few days/weeks or something.
lurkingmurking I also wore a maternity dress yesterday! It was such a gorgeously warm day out and I just wanted to be comfortable and enjoy the sunshine :)
