Which care clinic are you at? I know how you feel I'm nearly 15 weeks and you are always focusing on the next scan or milestone but 12 week scan is a buggy! I had to wait til 13 weeks for mine! I had the care one at six weeks then two at nine weeks due to a bleed and then 13. Been having some sharp twinges over the weekend so may well be sent back for another this week!
If it's any help my sickness tended to ease off at around 13.5 weeks although I was lucky and only had permanent queasy sickness and never actually sick. Comes odd days now but generally gone but it's replaced with tiredness and headaches
Oh the joys. Congratulations though very exciting time after such a long journey!
