Low baby

I'm 25 weeks today.  When I woke up this morning my belly was so low and she has been kicking me in my pelvic area all day.  It doesn't even feel like she is in my belly anymore just down in my pelvic bone area.  Is this normal,  why in the world is so so low already?? I asked my mom and my grandmother about this and they both said that she just needs to switch positions,  but it feels like she has been moving and switching positions all day and she hasn't moved up any higher... Ughh it is so uncomfortable.
