Morning sickness?

Has any of yall had morning sickness before missing your period or getting a positive test? How common is it?

I use two apps to help tract my cycle bc they can get off some how, sometimes. One app says I was suppose to start 3 days ago an the other say I'm suppose to start in a few days. I have had 2 neg pg test. I've been sick out of no where started yesterday afternoon, an has been continuous so far, after I was finally through this morning I felt so much better for about an hour before it all coming back. I've been having bad hot flashes the past few weeks, headaches, dizziness, an more tired then normal.

My husband thinks I'm pg as well as his coworkers but I can't let myself believe it till I see a positive test or ultrasound.

What is yall inputs? Sorry if it's a Lil tmi..
