Not feeling pregnant TMI

So I'm 7 weeks and one day pregnant. I have no nausea or morning sickness. I did three weeks ago but it completely went away. I've only had one or two cravings and that's it. I have been emotional but I don't FEEL pregnant. I'm scared that when I go to my doctor appointment I won't see him/her on the ultrasound. I have browinsh Discharge and I'm scared I'm going to miss carry again. Am I crazy? Have any of you who lost a baby feel like this with the following pregnancy? Am I just too scared too loose it again and that's why I can't enjoy or feel pregnant? Any advice or tips is truly appreciated. Thank you.
