11 weeks and 5 days still nauseous

Ok I'm still nauseous I was hoping it was going to be gone soon but if I don't eat something like every 2 hours is dry heave until I force some food in me it crazy I do take diclegis and it does seem to help I'm just over puking every other day and being sick ever evening like clockwork. Is this normal should I be feeling better yet I don't have another ultrasound until 13 weeks so I a bit worried
