Thanks for the well wishes guys.
I also suffer with HG although this pregnancy has definitely been my easiest. I've been on Cyclizine, PromethaZine and anti acid since week 4 with only two hospitalisations this time. I've never had blood in my sick though!
GP seems to think it's a stomach ulcer.
I called the GP receptionist and she said "is this a medical emergency?" And I explained the situation... she went "you've probably eaten beetroot." I said "no. I don't like beetroot and haven't ate since 6pm last night."
She said "you've almost definitely eaten beetroot" what the fuck
