ickle toothpaste; have you tried mouthwash? You're not meant to brush your teeth for 15 mins post spew anyway - enamel is weakened by acid in vom so to brush them then will damage them. Mouthwash would be fine immediately afterwards. It will certainly help you to feel fresher post spew. As I've mentioned before, Aquafresh My Big Teeth Mouthwash worked amazingly for me - it got to the point that smelling the mouthwash worked to help me feel less sick! There's also a fennel toothpaste that some people find works.
iknit have you tried ice lollies/ice pops (calippo ice lollies worked for me, especially the lemon and lime - in fact, we replaced our freezer a few weeks ago, and the top drawer was full of the orange flavoured calippos!)? They might help with the fluids. I found that swallowing liquids, even small amounts, was enough to make me sick, but sucking on ice lollies released such small amounts of liquid at a time into my stomach that my stomach could cope with it. I'm sorry you're struggling so much - A&E might not be the best place on a Friday night... do you have an early pregnancy unit you can access? Otherwise out of hours might be worthwhile (though that all goes through NHS111 now) - at least that way you might be seen without having to spend ages surrounded by drunks in A&E. I had a couple of trips to out of hours and they were brill - they know seeing you there is cheaper for NHS than an admission, if nothing else!
mrsamerican your GP can take a running jump re finishing with ondansetron soon. My GPs was the same, weekly prescriptions from week 7 - 20ish, then I saw a senior doctor, and he put it on repeat prescription for me, and a prescription was 2 weeks worth. It can be so scary when you're heaving so much that you find you can't breath, much sympathy.
mango your GP is talking rot, as you know. It's so frustrating that when we are at our illest is when we need to fight people the most for the care that we need. Are you able to take your partner to the GP with you, with a copy of the NICE guidelines (linked in the 1st post) - these make it clear that meds are not to be kept til 12 weeks, and that the aim of care is to help women have as normal a life as possible. Congratulations on the pregnancy, and sorry that you're feeling so awful so soon.
sleepy did you make it to the park? How was it? Are you ok?
amysmummy I think I've missed something, but reading through what others have said, you need to be at home - your daughter needs continuity and you don't need any extra stress. I hope this doesnt exacerbate the HG at all.
silk I'm a one time only mum (at the moment - constant battle in my mind, but I've got a bit of time, little boy only 23 weeks) so can't offer advice re subsequent pregnancies. Anecdotally HG happens with subsequent pregnancies and can be worse. However, I have spoken to a couple of women not on this board who haven't had HG a second time - I think the women who end up here are the ones who suffer, those who don't have it second/third/etc time, don't end up back here to tell us about it. I'd suggest having an appointment with a sympathetic GP (esp. if your practice has one with a specialism in womens health etc) and getting a care plan in place. That way you won't have to fight for care when you need it most, rather can refer to the careplan on your notes. That's what I will do if I can convince myself to go through it all again!
