Symptoms stopped at 5 weeks?

I’ve had a miscarriage before at 10 weeks and I didn’t know it happened so I’m pregnant again and paranoid now. I had stomach cramping and some pain in my stomach at 4 weeks, now I’m 5 weeks and all symptoms have gone away. Is this a sign of miscarriage? I have to wait until mid August for my 8 week first sonogram. I hate waiting not knowing if I miscarried.
