4w5d and struggling

Hi, I hope all my friends on here are doing well. I’m just posting really looking for some advice and insight from others who may have suffered/be suffering as I am just now…Currently only 4w5d, but struggling massively the past 3 or 4 days with horrible nausea and vomiting that lasts all day and night. The actual vomiting I’d say is maybe just 5 or 6 times a day on average but the feeling of nausea is just constant and never goes away…It’s making me feel bad enough to the point I have had to call in sick to work the past 2 days. I feel a bit stupid and pathetic for telling my boss I already feel I’m struggling so early on and if I’m being totally honest I don’t feel I’m being 100% believed on it all but my neighbour even said to me yesterday that I looked awful and as though I’ve lost some weight. I can’t eat anything really other than ready salted crisps or salt crackers, the smell and thought of other foods alone is enough to make me gag!!! Anyway I’m just looking for some advice as to what else I can do, I’ve got an appointment with my doctor later on today and have to bring a urine sample in with me. I’ve tried ginger tea, mints, crystallised ginger and just trying some breathing techniques as well so I don’t vomit as I feel genuine anxiety when I feel like I’m about to, it comes out of nowhere, but it doesn’t feel like those things are really doing anything for me. This is so debilitating and I feel I can’t live my life as normal because of it. I’m just exhausted and not to mention feeling guilty because I feel like I can’t even walk my dog anymore. I’ve been having pains/twinges too as of yesterday which aren’t really painful as such just uncomfortable but I feel if it wasn’t for the extreme nausea and vomiting on top of that I would be able to carry on as I normally can. I’m stressing myself out about having to call in sick to work given how early I am but I genuinely feel so awful and am really hoping the doctor can prescribe me something to help. Is it possible to have HG this early? I’m not sure that’s what I have but I certainly feel rough enough that I’m starting to consider the possibility 😟🤢 any advice would be so appreciated, thanks to everyone who’s taken the time to read this to the end x
