Sounds normal to me, have you had your blood taken recently? You could be low on Iron, I had never been low on iron before until I got pregnant, as soon as I started taking iron tablets I felt so much better! Definitely see a Dr they will be able to help you out
Definitely sounds like some rough morning sickness. It's normal. If it gets really bothersome call your Dr they can prescribe you something for it if natural remedies don't work :)
Just morning sickness love. I had it my whole 9months from day 1 to the day I delivered with my daughter.
Crackers , gold fish , sprite , Powerade , Sonic cherry limeades were all my go to's lol
