Congratulations bootheunicorn!
I had morning sickness from 8-22 weeks, still get the odd bout now at 25 weeks though thankfully it tends to be a case of feel sick, throw up once and all good! I found yogurts helped, apparently because they're milky they're pretty soothing for the stomach (something like that anyway!) Despite being 28 and not having had them since I was about 4 I was drawn like a magnet to petit filous and they're actually the only yogurts I'll eat now, they still taste amazing. I know you said you aren't keen on ginger but along with the yogurts I drank ginger and lemon tea, it's not a really strong flavour and the lemon helps lift it a bit as well so that may be worth a try as well.
I was about 14 weeks before I bought anything, a cot that was on sale and saved us about £200 compared to buying full price. Wait until the sales are on about Christmas time and see what you can pick up then and save a bit of cash, easier said than done I know! But that said, what will happen will happen and buying a pram at 6 weeks wont jinx anything. Even though none of your friends have kids you'll be amazed at what you'll get offered from people, we're getting things from friends of our parents who have had baby stuff tucked away for the last 20 odd years but is still in perfect condition! Also getting a swing crib (rather than a moses basket) from MY nana (age 80!) who bought it for my brother when he was born in '83, all 6 of her grandkids used it and now her first great grandchild will get to use it too, shes thrilled to see it going to the next generation. The only thing I would never use second hand is a car seat, even if it comes from a friend you just don't know that it's in 100% tip-top condition.
And don't worry, no one knows what they're doing, my theory is you only need to know three things. Feed it, change it, do your best not to kill it! But then this is my first too so what do I know?
