Wo, slow down hun! You're gonna end up with extremely high blood pressure so you need to chill out big time! If there was anything untoward on your blood tests, you would have been notified by now. When the results are returned to your surgery or clinic where your blood samples were taken, they would have been checked for anything abnormal and you would have heard from your midwife immediately so stop worrying! They are routine blood tests, something that every pregnant woman has done, and more than anything, they are helpful to your care provider to show them that you are healthy and not lacking in anything such as iron which may place you at risk when carrying a baby, as they can place a great strain on your bod! They can, of course, help to diagnose things like downs syndrome but again, this is all just routine and really nothing for you to worry about.
I suggest you go and put the kettle on and sit down with a well earned cuppa and please don't sit there thinking something is wrong - no news is good news, as they say, so just forget it and start enjoying your pregnancy!
