Early irregular periods now!! 😞

Victoria
Hi ladies, for the last 2 months my period had started 7 days early then this time 4 days early I've unfortunately had 3 misscariges in the last 10 months do you think this could have something to do with it?  My periods have always been normal before 28 days exactly! I've got an appointment with a gyno at end of this month but wondered if anyone else was experiencing the same?
