Words of encouragement please

I had a miscarriage in march and I found out I'm pregnant again a couple weeks ago. But, I can't help but feel distant from the situation because of the miscarriage. I don't do anything different with my days because I feel like this time will be a huge disappointment as well. I don't even feel pregnant. How does one get out of this funk? I want to be happy, but I need to see a heartbeat or something to cheer me up. I want proof that everything is ok so I can be happy again. Is that wrong to think that way? Someone help me get out of this.
