Hi there..Itching is there ...can happen due to acne ( hormones) ,or dry stretchy skin... I am in my 18th week n I tell you the only relief is by applying a good natural moisturizer parabenfrei and apply at night too.. I can't say much for vomiting because I didnt have.. I tried to avoid sugary foods and carbs and maybe that was a factor.. Also folic acid tablets over the counter can trigger vomiting.. I would suggest if you find organic ones free from maltodextrin or dextrose.. Sea band is help ful for vomiting and ginger tea chamomile .. and chilled water sips can lower vomiting .
Vomiting is normal in first trimester
