Just worried

This is my second pregnancy, symptoms are way less this time around. They come and go. I just can’t help but feel like something went wrong when I have no symptoms. Did see the heart beat at 6w5d and am at 8w now. But the lack of, and the fact that the symptoms all come and go… worries me.

I did have one miscarriage before I had my son and i noticed a lack of symptoms, then dreamt of bleeding. The next day I actually bled so I called the OB and they said there was no heart beat on the scan and to prepare… ultimately that led to miscarriage at 7 weeks
