Suu balm is my friend since right before I found out I was pregnant. that's because I have hives and allergic reaction when I just conceived due to hormonal changes. After a while like almost 1.5 months, my hormonal is a bit more stable and the hives went away. Now in my 3rd trimester I still do not get any reaction or hives. I still use Suu Balm as lotion for my belly because it's expanding and it's relatively itchy at times. Hope this helps.
You can come back to your gynae/doctor for alternative of prescribe medication. During pregnancy because of hormonal changes body tends to get dry, itchy, red spots. I have been prescribe with steroid and moisturiser. But never have I been using steroid. I solely depend on moisturiser 3 times a day. That's QV cream which helps a lot.
I had something similar and gynae said it’s probably due to hormones. I used suubalm as well. However, my gynae did give me the cream with little steroids in it just in case.
