Itchy as hell

Anyone have a belly that unbearably itches?? I am 40 weeks on Monday, 11/20. I️ have already been to the doctor about it and they say it’s just from skin stretching and to take Benadryl or use a Benadryl cream for it. But they are not working. I️ have used coco butter and coconut oil. NOTHING WORKS. I️ can’t sleep at night the itching is so bad and i can’t even concentrate at work it’s so itchy. I️ hope someone has a found a relief for this that will work for me 😭
