Does my dream mean anything?

Last night I had a dream I had my FIRST period I was at church in a white dress then when I got up there was some red stuff on the bench and on my dress I suddenly appeared at a house where my grandpa was hurrying me to get on the car and leave. My girl cousin suddenly appeared and gave me some pads I went to put one on and it filled up fast then I knew it was my period. - the end I don't know if they are cramps or stomach pains I also get alot and when I say alot I mean alot of discharge since a year and half and got some hair down there and have 34 A I'm also 13 1/2 my mom got her period at 14 1/2 so can the dream mean I will get my period or coincidence and no I have not been dreading or stressing on the arrival of it
