Unsure if false positive

Hi guys! I actually got a positive from clear blue on Friday but either a ridiculous faint positive or I’m hallucinating and it’s a negative. What does that mean? 😰 but it seems like my body is experiencing pregnancy symptoms such as cramps, tender breasts & nausea once in a while! I’m due to see a doctor I’m 5 days but I’m going nuts worried that it might be a false positive
