Married & pregnant with first child

When I found out I was pregnant my husband didnt seem happy at all... which a few months prior to he was the one that said he was ready for a child. We have been together for 6 years and married for a year. Now that im pregnant he seems to have any interest in how I am feeling or anything... he has came up with some names but that's about it... He doesnt seem excited at all or ask any questions.... We have had a couple big arguments in the past week....i feel like im at my wits end... Has anyone gone through this??
