I am only at 17 weeks and I sleep for maybe 1.5 hours a night. I have an extremely arched back and I think it's making me very uncomfortable at night. I'd like to get one of those nice big funny shaped pillows but I worry the area around the neck would be too big and cause even more pain as I've heard certain pillows are way bigger than others. I am 5'3" and pretty small. Does anyone have any good recommendations? Thank you:)
