Weird question but need answers

So I was pretty sure I was pregnant but didn't want to do a test until I was due. But yesterday spotted and that was what I thought was a good sign but today started again and got heavier. Due to having a chemical pregnancy last month and misscarage the month before I figured I would do a test so I would no weither I'm going through it again. It came up with a line straight away but never got colour. It is 5 o'clock at night here so haven't waited 4 hours like I should have but wanted to do it before hormones change. Am I going through it again?
