Oh it’s been busy for everyone! So sorry to hear of hospital trips and pains, but I hope everyone is feeling better soon 
brandy I echo the suggestion of taking it easy and getting signed off, if you can. It’s quite stunning just how much even basic activity can make the sickness worse 
I get by most days because I literally do nothing - I sleep, I lie in bed, sometimes I try to sit on the sofa (and sometimes that’s too much!), I still have nausea but I usually avoid the vomiting if I’m basically sedentary (I vomit sometimes, but it’s not daily which makes such a huge difference because it means I’m not straining my muscles so much, or getting dehydrated, or peeing myself accidentally... ahem). It makes me feel a bit useless, but I’m coming to terms with the fact that I just need to look after myself until whenever I can do more. I do hope you’re feeling better though.
Elkie I stuck to cyclizine but I’m in a similar spot, I probably spend 80-90% of my time feeling nauseous and rough, I sleep a LOT, if I’m not sleeping I’m lying on the bed with the blinds drawn (like some sort of melodramatic recluse 
). My GP was really straight with me and said, “The thing is, it’s hard for us to control everything - so you’re not vomiting, you’re keeping food and drink down, which is really good. All you can do now is rest. If you can rest, that really would be the best thing to do”. Perhaps there are other meds, but I get what she was saying - I’m not at risk as such, like of dehydration, which is awesome from the medical perspective, but obviously still rubbish from a quality of life perspective. But their priority is the medical side more than the QOL side (my last GP was also really honest about this!). So I’ve stuck this one out. As it stands I had a day 2 weeks ago where I basically felt normal, and yesterday was pretty good too, so they do happen. I immediately notice the difference, as does DH - apparently I don’t normally get out of bed so quickly these days so when I do, he knows I’m having a better day!
Lucinda my cats are finally nursing me! they’re always lovely but they definitely have a soft spot for DH, he’s home during the day and feeds them (and talks to them) so they’ve developed a close relationship! However the last few evenings they’ve been coming to sit on me instead, which is a novelty.
eallison can you stomach things like smoothies? When I was first thinking I’d be going back to work (before I realised how serious all of this was), I was nervous about what to eat during meetings as I often have meetings over lunch or have 7 minutes to knock back some salad between things, and I knew that wouldn’t work. DH suggested bringing drinkable nutrition, which I thought actually sounded like a really good idea. We have a smoothie maker which helps, so I could just use things I could tolerate. I suppose drinking soup from a thermos mug, if you can tolerate a soup (something smooth and inoffensive maybe?), all depending on what you can actually stomach of course.
Went for our first proper scan yesterday (dating scan). Baby is not compliant! Wriggled so so much and took three attempts to get all measurements (they’d send me off for 20 minutes whilst they saw another woman, then would bring me in again to try). Sonographer was really good about it though and very good natured, laughing, saying he was determined to get these measurements, and we did get there in the end. Only took 1.5 hours EDD has moved very slightly, now expecting 1 September (so glad it went slightly earlier and not later!).
4yo DC2 has come to see me, DH drops him off after nursery pick up on way to get DC1 from Primary when I’m awake, he comes straight up to hang out with me in bed, it’s lovely. Reminds me why we’re doing this!
