Still possible?

Ashley • Mother to 2 beautiful girls.
I couldn't help but test earlier than I said I wanted to the 26th. I ended up testing today at 11dpo and got a negative. My period is due Sunday, but I have a lot of early pregnancy symptoms. I'm not even trying to think my pregnant, I just don't feel like this is our month. I hope it is but doesn't feel like it. What are the chances that since my temps are still high and even though I had a negative test, I could still be pregnant?! TIA
