Can't be excited.

I can't be excited about my pregnancy. I miscarried back in March from a chemical (assumed) and I just found out I'm pregnant again. I'm not even due for my period for a few more days but my prego test are unmistakable. I know it's early but I feel like I can't be excited or anyone else can because it's still not a "real" pregnancy. Because a doctor hasn't confirmed and an ultrasound hasn't been done. I want to be happy and excited but everyone around me is making it like I should act as if this one will end too. I know I need to be patient and not set myself up for disappointment but I just want to be happy and look foward to my baby. If anything I feel like this pregnancy is depressing me because everyone's putting it in my head that I can't get excited until it's confirmed. I don't know what do to do I was fine a few days ago now I'm worried again. This is gonna be the longest 3 weeks of my life...
