Coconut oil. It will treat stretch marks also.
Freezing water is all that helped me or rubbing ice on myself to freeze the part of my body that was itching lol! Piriton helps sometimes.. I dunno if they have that where you live, its an antihistamine
Get checked for cholestasis.. I had that and I was in hospital over a month and induced at 37 weeks, its fairly rare so make sure you tell your doctor to check you for it asap cause its fairly serious... Not trying to scare you but it can kill the baby but once you have a lot of movements then don't worry! so make sure you get checked for it straight away and keep us updated :)
You should also consult your doctor since there is a condition pregnant women get during pregnancy that causes itchy skin
Calamine lotion is great ! Its ment for chicken pox and poison ivy so its great on itchy skin :) u could also use coconut oil its been working great on keeping my skin hydrated
Gold bond really helps me
