Just when I thought morning sickness was going away..,

I'm 11 + 3 and have had pretty consistent nausea since around week 7. I was mostly irritating all-day-nausea, and I was throwing up about twice a week, particularly in the mornings after waking up. During the latter half of week 10 and beginning of this week, I felt much better, with just occasional nausea and no throwing up. Then yesterday everything went downhill. I was incredibly nauseous alllll day, felt miserable in the evening, and haven't been able to keep anything down since dinner last night. I'm hoping this is morning sickness' cruel finale before things start feeling better second trimester, and that this won't last the duration of pregnancy. Anyone else in week 11 and still feeling really queasy?
