Congratulations on your first pregnancy! Sounds like you are experiencing the normal physical ups and downs so far.
In regard to the hubby, it does sound like he's being insensitive. However, I do have a few suggestions that might be helpful (full disclosure: I haven't read all of the other responses yet so hopefully it's not duplicative). First, have you tried talking to him to see what his fears, worries or concerns are? Sometimes you think you're disagreeing about one thing but it's really a disagreement over something else. Perhaps he's really worried about how not having help at home might negatively impact his responsibilities at work or ability to wind down from work. Or maybe he's worried about being able to adjust to the lack of sleep, potentially constant-crying, or any post-partum health issues that you might have once the baby arrives. It could be the case that just as a lot of people are probably bending your ear with horror stories, advice, recommendations, etc., he's getting the message from his friends/family that you really need to have someone else there to help out.
Second, maybe a good compromise would be to just have someone come by for a few hours at a time. If Mom/friends aren't able to do it, what about a sister, cousin, aunt, work colleague, or hiring someone? And if you really don't want anyone else caring for your baby, you could hire a housecleaning service to come and clean for you once every few weeks or so, or look into some other services that might make the adjustment easier, like grocery delivery or one of those places that provides a fully-cooked meal for dinner.
I think one of the important things to remember is that your spouse is not the enemy. :) He probably has his blindspots and flaws like any other man, but one of the great things about being a wife is that we can help them navigate around those with the right approach! I wish you all the best as you start on this next wonderful chapter of life.
