Unclear pregnancy test

[Belfrost]

Hi, so I was due on the 25 of this month. I took a test this morning 31st and straight away it came up positive. However on the control window only half of the line appeared. The bottom line was bold, but the top part didn't appear until almost an hour later. I don't know to take it as a positive or faulty test. I have a few pregnancy symptoms, such as frequently weeing, sensitive to smell and tender breast.
