CONCERNED

So I've been suffering extreme nausea since about my 7th week of pregnancy. I'm now 12+4. I have some good days but mostly bad. I've lost almost 30 lbs in that 5 weeks because of eating and then throwing up right away. I take my prenatals when I eat, and try to hold it all down as long as possible so it can absorb, but I just can't! I have morning sickness pills, but holding them down long enough is also becoming a problem. Anyone else dealing with this? :(
