Doctor is NO HELP!

I called last week about my BFP but they didn't give me an appointment until the 28th. 
No blood work or anything until then. 
All I want to know is everything moving along on smoothly. I'm about to be 7 weeks. 
I was cramping on one side yesterday and I almost went to ER. No bleeding but I'm so scared of missing something. 
I went with a friend to take a test at a clinic so I did it too for fun. Well the line was super faint too. Now I'm amazingly paranoid. Any advice?! 
Called the doc and they said the cramping is normal. Yes I get that but can I get an understanding of where anything else is at?? I'm losing it with this doc!!!
