My boyfriend couldn't get it up today

My boyfriend and I have been together for three years & I can tell he always enjoys sex with me every time we do it & so do I. I'm 11 weeks pregnant with our second child so my hormones are going crazy so I tried to catch him before work. This is the first time ever he had "limp dick" I was sucking & spitting & gagging, doing the things that will drive him crazy all the while it wasn't all the way hard so it was just awkward because I see him paying attention to the TV. So I tell him, we don't have to do this it's fine. But he insists, so I get on top & it's flimsier than before & I look at him I ask if he is even enjoying this so he just tells me to get off & goes shower. It's weird because he's never done that, he's always in the mood & today was just the first time nothing I was doing was getting him excited & again I'm pregnant & hormonal so all I did was cry lol. Probably an overreaction but I felt like the vibe was off & he's making me feel like I'm crazy.
