Distant husband

Liz • I`m a stay at home mom of my daughter Sophia ❤️. I`m married to a wonderful man and we live a wonderful life❤️
My husband and I decided to TTC in January and now he seems distant. Is that normal? He keeps saying he's not feeling anything like that but I know my husband and I know something's not right.
Should we wait until we get to the bottom of this? I don't want to make a baby and feel so alone during pregnancy
