Did anyone have complications?

So I’m wondering that if anyone that suffered with sickness all through their pregnancy experience any complications?

I have had the sickness over a month I’m 12 weeks right now I’ve been in and out of hospital due to dehydration, but now the hospital has said that you can’t do self referrals which I did twice after my 1st admission. I am not keeping anything down I’ve started throwing up blood and I’ve had pinky discharge, I told this to my gp dr to see if I can get admitted that way as that’s the only way they said they will admit me and they don’t see it enough for me to go in! So I’m suffering I can’t eat or it comes up 5 mins later which is horrible as I’m choking and gasping for air as I am struggling to breath when I’m standing or being sick, I’m weak I’m dizzy and my body goes numb when standing and I’m worried the effect it’s having on my baby so help and advice would be grate many thanks
