So sad

So the past few weeks I have had more than a dozen different people (strangers, friends, co-worker etc) ask me if I am pregnant. Today i was asked when am I due by a customer. It normally would just offend or annoy me as I politely reply...however today I got the results from my blood test back...negative and an hpt came negative as well. I'm at CD 35...1 day late and this just got to me today. I had to sit in the bathroom on my break and just broke down. After 6 months almost 7 I have my hopes up so much this cycle. And I know it isn't over until it's over....but it was just upsetting. Why has the question started all of a sudden...my body hasn't had any super noticable change even.
