Early symptoms and a caring fiancé

I'm only 7 weeks along and have been having symptoms since about week 5. Bad cramping, severe nausea and some bad dizzy spells. A few days ago back pain started, pretty sure from how I sleep. My poor fiancé doesn't know what to do to help, we get married in 10 days and he wants me to enjoy our wedding. Currently I can barely make it through a work day. The sweet sweet man that he is asked some nurses at work who have had children for any help. I love this man so much
