Confused and starting to lose hope!

Charla
Ok, I'm 15dpo, AF 2 days late. No symptoms at all, which is weird, I usually have really tender breasts, bad cramps, bloating, and fatigue. So I finally took a test today, figuring 2 days late with no symptoms was a safe bet, BFN, not even a hint of a line. What is going on? Could I still be pregnant? Or is AF just late? It was early last month. I'm so confused. HELP!
