12 Weeks still having Nausea & Vomiting !

Raven
I am 12 weeks 2 days & still have nausea and vomiting. Mostly between the hours of 8pm - 6am. I have it during the day as well, but it is so much worse at night. Every night it never fails .. Is this normal ? I thought the sickness was supposed to lessen toward the end of the first trimester. Please help ! 😩
