10 weeks 4 days feeling better out of no where

So I was intensely sick and exhausted all the way up until 10 weeks 2 days to the point where I could hardly get anything done....I woke up yesterday on the 3rd day of my 10th week and had almost no nausea and with much more energy! Of course I'm relieved to be feeling better and able to get more done but I can't help but be a little worried that most of my symptoms seem to have disappeared...
