Another BFN...?

So I'm starting to lose hope but even worse I feel like must be crazy. I was so sure that I was pregnant and felt so many signs. Fatigue, headaches, mild cramping a week before AF, severe bloating, and sensitivity to smells. I tested at 6dpo but knew that was way too early and got a bfn. Tested again on the night of 8dpo which was another bfn. Tested early this morning on 10dpo and this was the result...looks like another bfn to me. So I'm starting to get discouraged even though I've been reading that 10dpo is still a little early. I guess I expected to get at least a faint positive on 10dpo...
