I heard itching could be a sign of hellp you might want to talk to your doctor
Talk to your doctor to get blood work done it can be cholestasis I was diagnosed this Wednesday and now baby needs to be monitored every other day and I have to be induced because when you have this you cannot go full term as it causes complications for the baby
Also, try not to scratch !! I heard that its also caused from your skin stretching, and scratching increasing the chances of getting stretch marks. Not sure if its true, but try avoiding it anyway!
I would recommend speaking to your midwife and having some blood tests done as I had itching and thought it was nothing, I mentioned it to midwife and she did blood tests turns out I have obstetric cholestasis.
Oh yeah. I've been really itchy since winter started, mostly due to the dry air and your skin around your tummy and back is growing which I'm sure adds to it. Lotion daily or multiple times if you have to.
