Pregnant... Now what?

Okay so for the last twelve months my husband and I have been engaging in somewhat 'kinky' sex. 
Anal, bondage, force, toys, double penetration, etc etc... Basically I was his little 'cum slut'... We'd get drunk  and go crazy. 
I've recently found out I'm pregnant and I'm a little concerned this sex with stop... I won't be considered his 'little slut' and we will both be left in satisfied..  Or he'd look at me in a different light.... 
I've mentioned it to him, but he thinks it'll be fine... However, ever since I found out I was pregnant a week ago, we haven't had sex... He's been tired...
We are so excited for this baby, I guess I'm just concerned that sexually... Things will take a down turn. That worries me and also makes me feel a little uneasy... I don't think he'd go elsewhere but I don't think he'll be getting everything what he wants (and I want) from me now... Any ideas or advice?
