morning sickness that is worse than before?

C
Has anyone's morning (all day) sickness got worse through out their pregnancy? I had morning sickness from weeks 8-15. Slight nausea that would make me feel like I was hungover, threw up a few times, a bit dizzy, but mostly manageable. Now I'm almost 19 weeks and I'm feeling more sick than ever. Terrible headaches, anything I eat just hurts my stomach and makes me want to throw up. (I've puked three times in the last two days). At first I thought maybe I had the flu but I didn't have a fever? Has this happened to you??
