Yes it can. I had it ki da bad in the befit never really went away but there were times when I had a break now it's coming back and I actually am good in the mornings but mid day and towards the night I'm sick.
Yes. People think it only happens in the beginning but it can happen at anytime during your pregnancy
I have no idea... But i never got morning sickness... And now at 26 weeks i have days I cant look at food... Its so odd :(
