Feeling ashamed of my body

For awhile I have been feeling ashamed of my body. I'm 33.2. Every time I looked in the mirror and applied cocoa butter, I started to complain. My boyfriend has always reminded me of how beautiful and amazing I am for being able to carry another human in me. On Monday, I began to feel confident in my body. I wanted to show it off. I sent my mom this pic asking if it was too much to post on social media. Her words knocked me right back down. How can I build my confidence back up? Is it really that bad?
