Severe itching!

I have been suffering with severe itching for about a week now that I think has been getting worse, it is defiantly worse at night and I’m struggling to sleep with it, its all over my body and I can’t stop scratching.

The midwife is having me in tomorrow for a bile acid test to check if it’s a liver condition you can get in your last trimester of pregnancy but is there anything I can use in the meantime??? She told me to just have a cool bath or shower to soothe it but that doesn’t help at all, I’m sitting here scratching like mad 😭
