Negative results but no period

Janelle
I'm very confused, and needing some advice. I am now 11 days passed my expected period of the month. I have very regular cycles and have been TTC for 6 months now. I am having so many pregnancy symptoms, but every test I take is negative. I've taken tests early morning, during the day, you name it. And my body feels different as well. What do I do now?
