Oh my goodness! I have just seen your thread.... Congratulations!!! What wonderful news for you but what a shambles it has been for you. I would definitely be making a complaint. As the other girls have said 4-6 weeks is very early and you really can't see a lot. I'm so glad that you got another opinion and that they did bloods for you. That is generally the best way to tell. Let us know how you go!
