new identity as pregnant/mom

I am extremely happy to be pregnant with our rainbow baby and I can't wait to be a mom but I find myself struggling a bit to find my identity now. I feel like it naturally changes you and your life. I have been having a hard time feeling sexual with my husband while pregnant, partly due to low sex drive but partly because it's hard for me to associate pregnancy and motherhood with being sexy. I know this isn't actually the case and it's in my head but I find myself thinking of other things I enjoy or do and saying to myself, "that's not something a mom would do." Anyone else feel like they struggle to find their new identity as a mom? I look forward to being a mom but I also don't want to lose my own identity or how I am as a wife, friend, etc.
