Do periods sync up with different girls when you live with them

Brenna
OK so I moved in with my sister and it seemed that my period changed its course to match hers. Then my little sister and mom moved in and my period changed again. But now we have our own place and it's just my fiance and I. I have been starting my period around the 5th but nothing yet. Is it because I'm not around my sisters or my mom anymore and my period is changing its course?
