Painful sex

So I’m almost 33 weeks and tried to have sex with my husband this morning, but as soon as he even tried to put it in it hurt 😞 one all the way in and not moving much (or at all) everything was fine, but the pain started again when he tried to start going. The pain is more around the outside/entrance (if that makes sense), but still a little on the inside? Has anyone else had this? Did you talk to a doctor or just leave it be? I just feel bad for my poor husband since I’m hardly ever in the mood anymore and now this 😒
