Heart beat

Elisa • 11 pregnancy losses this is the last year we are trying
I have a question have any of you ladies ever gone to your doctors appointment and they didn't see or hear a heartbeat..
I went to urgent care on 9/3/15 at 8 weeks and they told me there was no heart activity and I would have to wait to miscarry.. I'm so devastated I'm trying not to lose faith... 
(Not to mention my hcg levels keep going up
