Am I going crazy?!?!?

So I have had terrible bloating, lower abdominal and side pains, heartburn nausea, fatigue, frequent urination so on and so forth. Well I took a test the other day and there was the faintest line. I took a few more and they where all negative. I went to the doctor their test came back negative. I came home and did another one and once again the faintest line barely there. I am due for my Af on Sunday the 23rd so still 5-6 days out. Am I crazy or what?
