Poor line progression

Morning, I know this is my anxiety seeking reassurance! However I found out I was pregnant earlier in the week but don’t feel like there has been any line progression. With my first it was visible daily that the line was progressing. This time round the tests are barely visible still and I think I’m about 14th o! Has anyone had this and gone on to have a successful pregnancy? I feel like I’m preparing for the worst but also driving myself mad in the mean time and know that’s no good for a healthy pregnancy!
