Symptoms going away...

For the past week and a half my nausea was sky rocket out the roof. Now I only get semi nauseous if I don't eat or grab a snack every like hour. Some are telling me that I'm the lucky one who only had it real bad for a short amount of time, some saying it will come back full force around 8 weeks, some are saying could be hormones dropping and meaning that I could miscarry. I am a little scared...Anyone have this happen? I have a little more energy during the day but fatigue is still kicking my butt and sore boobs. Food aversions and cravings are crazy. So I have other symptoms but nausea is scaring me a bit with what people are telling me.
