Loss of symptoms.

Hi All! For the past few weeks I was feeling very tired, bloated, nauseous, and gassy. Two days ago I started to feel better, and now I don't even feel pregnant. After a miscarriage last year, I am starting to get worried something has gone wrong again. We saw a heartbeat last Wednesday at 120 bpm which is normal, but on the low side. Has anyone else lost symptoms around 8 weeks?
