Having a hard time excepting my pregnant body....

I have no reason to hate or dislike my body. I am 29 weeks with my first and blessed so far with 0 stretch marks..... I love my growing body and I’m sooo excited to be a mommy!!! We tried for a whole year to get a BFP and I got it exactly 12 months later. Recently I have found my husband reading news articles about very attractive woman in lingerie (which usually I don’t think would bother me). But I know I’ll never look like them. Being 29 weeks pregnant and not being able to control how big I get (which I’ve only gained 18lbs so far) I just don’t know how to control my emotions.....I have started working out again to maybe help hide some of my insecurities or low self esteem....any other tips that may help over come this while being pregnant?!? I only have 11 weeks left to go. Any nice advice is needed and wanted.

P.S I am very athletic. I played softball for 15 years and power lifted for about a year so my changing body is very new for me.
