Feeling so insecure and unattractive

My SO's sex drive has gone wayyy down since I got pregnant.  He says it's the stress and depression that's come with his needing to grow up and prepare for the baby, which i believe is true.  
He really doesn't tell me I'm sexy or beautiful anymore.. And it's really starting to get to me.  We used to have an amazing physical relationship as we're both highly sexual people.  I do understand though what it's like to be overwhelmed and not be in the mood for sex all the time, I've been there too... but meanwhile my sex drive has shot through the roof with all the hormones and all the growing and changing in my body makes me feel insecure and need a little extra affirmation and love, which he apparently can't give me right now.  
I just feel very rejected and alone while being in a super vulnerable spot and it's very painful today.  Needed to vent.  Am i the only one?
Also extra details for context, I'm 20 weeks pregnant and he and i have been together a little over a year 
Thanks girls ❤️
