Stomach tightening during sex(19 weeks)

So my sex drive has almost completely diminished. Before the pregnancy we were like 2 little rabbits lol. Now I'm more so making promises that I know I'm not going to keep. I'd like to it's just not comfortable. Well when I do finally want to, I start to get into it and then my stomach tightens and I become so uncomfortable. I never told my dr that it happens during sex because this is just starting as we don't do it often and it's happened before out of nowhere. Do I stop having sex altogether?
