I have a question!

OK so I had my miscarriage in March. My period started in April, 19th. Cool, time to start over kinda thing. My period has always been regular. May came in, it was regular, started as expected. But now June is here and im a whole week early?? I find it weird, never had this happen.

Could it be the my body is still trying to adjust? Because of the pregnancy/miscarriage could I start having irregular periods?
