Nervous

Heather • Just got married in July 2013 and living the good life in San Diego with my husband and dog named Aggie.
So I'm probably over-reacting, but need to get something off my chest.
​I found out I was pregnant on 7/10 and was approximately 6 weeks along at that point. The week after that, I started noticing all the symptoms (cramping, sore boobs, bloated).  Literally on the day I hit week 7, they all went away. I am now beginning week 8 and they are still on and off (mostly off).  I have my first doctors appointment on Monday and I will be about 8 weeks 4 days.  I read all about these missed miscarriages and how they have no symptoms and am not planning for the worst at my appointment.  As much as I don't want to, I feel like I should plan for the worse and hope for the best.
​Does anyone have any advice or words of confidence that can make me feel otherwise about this appointment?
