Itchy tummy

Im currently 32 weeks and ever since start of 3rd trim my tummy has been itchy here and there every single day. Below tummy has like 3-4 small itchy bumps that wont go away for weeks. And upper tummy also itchy. Ive been using bio oil and palmer’s stretch mark cream from start of pregnancy and using suublam itch cream for itchy spots but doesnt work. What makes it worst when i use pants, ill have like a rubber band mark across my tummy, that will trigger the itch as well. It wasnt a problem before this. Is this normal ? Any way to make it go away? Cs moisturising my tummy doesnt work #FTM
