If baby is in pelvis does that mean he dropped

Bi

My doctor said baby is head down and into my pelvis which is probably why I’m feeling lots of pressure and pain down there. But I don’t feel like I’ve dropped. My ribs ache so bad at night. Maybe he can move back up when I’m laying down? Idk this is my third and unfortunately I’ve never been able to experience going into labor or baby dropping thanks to csections.
