could I be pregnant?

Samantha
I am 4 days late... I have some early signs cramping fatigue constipation and my mood is ALL over one minute I'm crying then I'm mad! I get pms but this is like pms on steroids... not to mention I normally love roasted red peppers in my salads and the other day they made me gag! Can I be pregnant I took a test it looked negative but there may have been a vfl? I'm driving myself crazy
