No more symptoms...

So, three days ago I found out I am expecting my first baby and I am already 7 weeks along. My period can be regular and irregular so when i was late i didn't think much. Looking back now, I was getting nauseous but that's something I've dealt with prior to this. I also had sore breasts, cramps, bloating and fatigue but I figured my period would be showing up soon. Took a pregnancy test and the test line showed up positive before the control line lol so these last three days ive been much more aware of my symptoms. However today when I woke up I didn't feel nauseous and my breasts were not aching or sore and i didnt feel as tired. And I've felt fairly normal all day..maybe some nausea but I feel that might just be because I'm hoping to feel sick lol I'm trying not to worry but it's hard not to..anyone else experience a fluctuation of symptoms?
