A WEEK LATE FOR PERIOD

The current cycle as for today is 37 days since my last period. Usually my period will come every 30 days and it's always ON THE DOT for the past 2 or 3 years? I already took a pregnancy test and all came negative. Was low-key hoping I was pregnant cause I had some symptoms but I'm not... Kinda worried about my cycle, it's never this long. Should I head to the doc to get it checked? Or should I wait for another week or 2? Anyone had this issue before mind sharing ??? Thank you. #AskingAsAMom #Needadvice
