I went through the same thing as you did when I was pregnant with my 1st. I was in the UK and there they don't offer you a scan till 12 weeks. And to make things worse, when I went to the GP after testing myself positive with a shop bought test kit, she just said she'll refer me to the hospital and that was it! She didn't even bother to test me again! So I waited till 8 weeks and had my 1st appointment at at the hospital and again, it was just another questions and answers appointment! It was till I was 12 weeks pregnant that I actually had some confirmation from the professional that I'm actually pregnant! But trust me, it was worth the wait!!!!!!! and I was told you don't see much at 6 weeks pregnant anyways.
