Ok, thanks. I should call her anyway. Hope everything is fine
If you're worried, you should call your doc, but nausea is common throughout pregnancy and even though it subsided, it's not uncommon for it to recur.
If it's getting more severe, you might want to call anyway, to make sure your baby is still getting enough nutrition.
I'd say go back to eating and doing the things that helped before but also call your doc for peace of mind.
