My periods have been regular for the last three years. I track for ovulation (temp and OPK tests) with the Flo app it’s consistent every month with me tracking everything. I ovulated on cycle day 15 (Jan 5th) and started my period on cycle day 24 (Jan 15th) I’m usually a 29 day cycle so I was surprised when I started so early (early for me). Now for the past two days I have been having light cramping and feeling a tingling pulling feeling in my lower abdomen. It’s sometime sharp but not to sharp it’s almost like a fluttering feeling. Does anybody know if I should be concerned?
