Am I just fooling myself?? Paranoid I'm paranoid!!

Hannah
Hey ladies, I'm paranoid that I'm tricking myself into feeling things that aren't really there and would really appreciate some level headed advice....!! I'm due on today but no sign. I've had cramps and sore boobs for about a week now. But this usually happens just before af. Yesterday evening I felt a bit sick but put it down to being hungry as felt better once I'd eaten. Today I have the exact same thing feeling sick. I'm worried I'm just convincing myself I have 'symptoms'? Please tell me I'm not going mad!!! Thanks!!
