Is it normal 4 sex to hurt a little bit as you exceed in your pregnancy????

I'm 26 weeks & 5 days & lately sex hasn't Ben exactly the same. I've done different positions & even the same one's I've Ben doing but it kinda hurts a little bit. Idk what 2 do about it because I enjoy sex & so does my partner but would hate 2 hear that it would be better 2 just stop having sex. Any advice is helpful. :-)
