I took an asda pregnancy test a few days ago as my period was late and I was worried that my seemingly bout of sickness could be a symptom and I got a very faint line. It was really faint but was clear enough to show my friend through a camera, she said it wasn't strong enough so I tried not to think about it but when I was ill again today (and looking online to see that a faint line is still a line) I took the other test to be sure and there was no visible line. They were both taken early afternoon and most probably I'd only be 3-4 weeks pregnant. Should I just regard this as negative or try a different brand? I'm also planning on going to the doctors as either way I'm not a fan of being consistently sick but would like to rule it out (so to speak) to stop myself overthinking.
