HELP: My symptoms stopped at week 7

Ling

I have been through with so many early pregnancy symptoms like breast getting bigger and cramp on the first weeks and nausea everyday...but today I woke up feeling nothing. I'm very worried about this because so many people think it's a sign for miscarriage. It has taken so many time for me to get pregnant, I really really don't want to lose my baby... Do u think it is normal?
