I never had morning sickness .. I'd feel nausea but never get sick .. The dizzy spells could be blood pressure dropping or sugar levels or the baby's blood flow
I got my nausea that was all day from 8 weeks till about 16 weeks.
It is normal this early. I had my only real morning sickness at 7 weeks, where vomiting occured. Now I am 8.5 weeks and feel fine. If possible eat a lite,healthy snack just before you get out of bed. Like a few mixed nuts or crackers that you can keep on your night stand. Don't forget plenty of water. But yes you are lucky as am I.
I'm 33 weeks and still vomiting like no tomorrow. You're very lucky
