Do you think I should talk to her?

So my grandma has been staying with us for 4 weeks now she has her own house and I don't understand why she has to stay here we live in a 3 bedroom house one for me one for my sister and one for my mom and dad my sister is pregnant so my grandma and grandpa have been staying in my room for 4 weeks it was fine at first but I'm tired of sleeping on the couch. When they have a perfectly good 2 bedroom house of there own to stay at but it's in the country so it's easier for them to get to work if they just stay here. She keeps saying "I'm thinking about going back but arianna(me) wants me here so I'll stay" I don't want her here I'm 14 on my period I can't get a goodnight sleep anymore I have 0 privacy I'm just tired of it and not to mention she's so condescending and always complains about everything and is always fighting with my grandpa she's planning to stay here in tell after Christmas! Should I talk to her I don't know what to do. Also I had a friend over and she mad is sleep in the living room and started fighting with my grandpa at 3 am
