Faint line on 1 test... Am I pregnant? Please help

Lauren

Need your help ladies! I’m 8 days late, boobs are really hard etc. I had a miscarriage in March at 11 weeks and 3 days (baby stopped growing at 8 week). I took a test from Tesco was negative, took clear blue one today and I’m sure it’s positive. Took another Tesco one and that one is negative. Do u ever get false positives? Please reply and let me know what you think... I’ll upload a picture of the test.
