Who Should I believe???

Jordyn`s Mom
So my period isn't scheduled to be here until 11/22/14, but I've been very moody, irritable, frequent urination (like lieterally every hour), tender breast, exhausted, and eating everything, so I took a first response test last Saturday and it was neg, but I figured it was too soon. So yesterday i took another first response and it came through with a faint line. So today I went to a pregnancy clinic, and they gave me two test and they both had a faint line, so the worker said it was neg, so I went and bought a three pack clear blue digital and it came back positive.... I'm so confused ? Who should I believe??? I can't get into my doctor for a few weeks
