Sick of these symptoms

Yesica
I need advice on what will help ease my nausea/ vomiting, headaches and backpains. I tried everything crackers for nausea, resting for headaches and pillows for my back but nothing helps. I do have back problems so now with the pregnancy I understand it will get worse but I cant use the cream I used to becayse im scared it will harm the baby it is a little too strong. my symptoms seem to be getting worst each day I even cried today of frustration I guess. I understand all these symptoms are normal during pregnancy so no im not asking how to get rid of them just how to ease them and help my days go by smoother.
