Could I possibly be pregnant?

Hello everyone.. I'm a little confused.. Me an my partner BD on all of my fertile days (fertile days according to glow) as well as days in between. I'm 2 days late for my period which is unusual, plus I usually have period cramps 3-4 days before my period is due an still haven't had any. I have a few symptoms but don't have anything showing on a HPT.. Is there any chance I may have ovulated later then what glow suggested? An could I still be pregnant? Anyone had this happen? Pregnancy test taken yesterday morning (1 day late for period)
