Hello, can anyone advice me please. I am only six weeks preganant but my boobs are incredibly sore, which they weren't before (5th baby) and my stomach is huge and when I did the pregnancy test it usually comes out with a faint pink dot but this time it came out with a DARK PURPLE one and my last period was a week early and only a few days long. Could I be further on than I thought or could it be twins or is this just normal, I should know as it is my fifth baby but it all seems a bit strange to me. Can any one advice me please. Sharon.
