Your partner should be there. At mine they went over genetic info and it was very informative for him...we women pick this stuff up throughout our lives and are more inclined to read up when we have questions, but guys may take more in in an appointment...it also makes him a part of the process from the beginning with the Dr.
My husband came. They ask ALOT of questions about both of you. I didn't really care. I wanted him there so HE could ask his questions too. Totally up to you hun
I went alone. Mine wasnt too long but they did ask a lot of questions and some pertained to his family history. I couldnt really answer those questions without guessing so it might be good for him to be there and i didnt think it was boring so he might be interested!
Maybe he can sit in the waiting room my husband did first visit is usually paper work and questions. .good luck hun
