@elm26 I'm currently on my 4th hg pregnancy, my newborn tips can't beat the others but HG recovery is really weird and if you're in a position to, I'd recommend when baby is here a few things. (If not your first rodeo, my apologies for my long post!)
Get an appointment with dentist booked ASAP. Explain prior to your appointment how much your teeth have been through, don't put it off, I've needed some of my teeth rebuilding so please get some treatment as soon as possible.
Don't worry about baby weight, enjoy eating whatever you want, at least 6 months, you're more likely to crave "real" foods, so hearty and filled with nutrition anyway. If you fancy it, you eat it!
Drink lots of water, your body had had minimal hydration, invest in one of those big beefy fucking massive bottles, don't just rely on caffine.
Vitamin D and multivitamins and spatone will definitely help replenish your body, you'll probably be absolutely fucked for iron once baby arrives. For at least 6 weeks take the spatone, because your tummy will have been ruined (especially with ondansetron), spatone is much kinder to you and will less likely to bring in more piles than Iron tablets.
Your hair will be fucked, if like me you're a bedridden hg person, you may even have dreadlocks, get DH to have baby, get a really really good trim. My hair fell out after hg2 but returned lush, its not forever. Also bleaching hair if you fancy a good change, please don't do it yourself if that's something you choose, please, your hair will likely just be so damaged. Days in the house with simply resting, stick some hair mask in, get some hydration.
Get a decent lip scrub and mask, I think revolution have combo on asos for quite good ones.
Spoil yourself a bit, obviously some people can afford a new bag, others can afford a new lip balm, but do something nice for you, hg is fucking awful and just remembering you're a person who can enjoy little things again may be helpful.💐
I've lost friends, (not social during pregnancies and people think they're being dropped because you have "morning sickness") I've lost jobs and I had ptsd from the vomiting. (One pregnancy was about 80-100 times a day, I was genuinely traumatised!) And I needed some counselling, if you're feeling anything like this, the week you have a baby, sign up with the NHS because having a baby makes you so vulnerable anyway and they should, ideally, have you some sessions booked then within 12 weeks.
I really really hope that you have a wonderful birth and very chill baby!
