7 weeks pregnant and 90% of symptoms gone


Ok so like the title says I’m 7 weeks pregnant. The past two weeks I had severe nausea, dizziness, and exhaustion, and by the end of last week I was throwing up excessively every morning til early afternoon. Saturday I woke up actually feeling okay, just tired. I drank a small coffee and suddenly felt good as new. No nausea, no tiredness or dizziness. Then today I figured it would be back, but i was able to eat normally with little discomfort and haven’t gotten sick in two days, and again I felt fine.

Is this normal or could this be a sign of low pregnancy hormones/ miscarriage?
