No AF & Negative tests

Amelia
AF was due on the 7th and I haven't even spotted. I've take 2 tests a week apart and they've both been negative. Feeling discouraged and confused because we've been TTC for 2 years now. This is my first post here and I could use some support.
My mom has been asking me daily if I've gotten AF yet. She really wants us to have a baby. I appreciate her being excited but sometimes it just makes me more sad. Help
