Blood tests UK


I had all my blood work done last Thursday when I went for my scan at 13 weeks. They said I’d get my blood test results back at 16 weeks. If there had been anything wrong would they have rang me by now? I presume if there was a problem they wouldn’t wait to tell me at 16 weeks?! I’m just wondering how long it takes for the doctors to get your blood test results back and if I can relax as it’s now been a week x
