Is This Considered Irregular?

QUESTION

Dear Midwife,
They say a cycle is 28 days. Do you calculate the first day you get your period to first day of the next month's period to get this number? If I sometimes get my period one or two days earlier, is that considered irregular? Thanks.

ANSWER

Yes, you calculate from the first day of one period to the first day of the next to determine cycle length. A couple of days either way is not considered irregular.
