Totally normal as others have said
I just wanted to add though that I think it's actually a good thing that you have those "what if something was wrong" conversations with your husband. Chances are everything will be fine, but it's good to know you're on the same page, rather than trying to figure things out in the event you do get some unwelcome news.
Good luck with everything, I hope you have a healthy and uneventful pregnancy!
