Anyone else is pregnancy denial?!?!

I'm 7.5 weeks along and had my first scan yesterday where my husband and I were about to see and hear the heartbeat! But I still catch my self longing and wanting to be pregnant!!! I am freaking pregnant! When is it going to hit me!?!?! I'm nauseous.. Breast pain, tired!! But I still don't feel like it's real!! We r so very excited but just feels like a dream!
