Dates all weird 😜

Shawna
If I normally have a 30 day cycle for my period and it comes on the 30th each month but last month it was 4 days early and came on the 26th shouldn't it have came on the 26th of this month? Or should I be expecting it on the 30th... Please help! I'm having white creamy cm instead of the white pasty sticky stuff before a period and some cramping here and thereÂ
