Help! I don't know what to believe

Ash
I took 2 at home pregnant test and they both had faint lines so I made an appt with my doctor she said the test was Negative ! So crazy I FEEL pregnant .. Then I went home and took a clear blue weeks indicator.. Obviously I want to believe what my doctor says but I thought these tests were accurate?? I'm so confused. Is it because it's too early? (Sorry I know it says pregnant, I'm just really unsure)
