Loss of symptoms

I just started my 8th week and we were lucky enough to see our bean with a strong heartbeat at 6 weeks 3 days. I have had little nausea and boob tenderness, mostly I am just really tired and moody. I get up once or twice a night to pee. Today I don't feel nearly as bloated and earlier this week I had cramping... Nothing major just like my period sometimes on one side. Since then not feeling really pregnant? Seeing RE on Monday. Anyone else? With a previous M/C I am just scared!!!
