Could I still be pregs?

Jessica

I'm 4 days late.....(supposed to have started Tuesday) and I'm usually like clock work

Pregnancy symptoms;

Nausea

Painful breast

Clear breast discharge

Sleepy all the time

I ate tomatoes (& I HATE tomatoes)

Smell sensitivity

....but I tested Thursday and today...both are BFN!!!

My husband and I have been trying for 7 months...so scared to be excited.....

Thoughts?
