Is this something I should worry about?

Maryanne
Ok so I have had really bad morning sickness since the beginning of June I'm 12 weeks on Thursday and two days ago it just went away! But I have had really bad migraines and maybe nausea once or twice! I notice I have more energy and  my Brest are not as sore and I am not as bloated  it's starting to get me worried! Could something be wrong? Or is that normal?
