Is this morning sickness?

So
I lost a baby at 7 weeks in Jan 2017. That was my first pregnancy. I became pregnant again in April 2017. I'm now 7-8 weeks pregnant and will be going for my first ultrasound tomorrow.
I've been a bag of worries ever since the BFP a few weeks ago.
A few days ago, I started losing my appetite gradually and has developed a strong aversion towards meat. 
I don't feel nauseous nor do I vomit. At most, I feel a little bit queasy, but certainly not enough that I think I'm going to vomit. Is this morning sickness?
I'm worried because I felt similar things in the days leading up to the miscarriage.
