5-6 days late and going crazy!

Melody
My cycle is usually 30-31 days long. I am not 5-6 days late with 4 bfn (Cheap Internet test), 2 negitive opk, and my cervix is so high I can't reach it. I have a 19 month old so I still remember being pregnant, and I feel pregnant. My breast feel full, I have on and off indigestion and I feel like I have butterflies in my stomach! If I am just really late, this is a cruel joke! Should I stop testing until a pos opk? (I have a mini stockpile) I don't want to go crazy! Any advice would be great. Thanks!
