af 2 days late

So AF (Aunt Flo - menstruation/period) was due on Tuesday. Still no sign. I don't even "feel " her coming . I've checked my cervix Tuesday, yesterday, and today, and all three times I've checked, i had no spotting , checked this morning and i did which makes me think my period is coming. my cervix is high closed and firm . but obviously it hasn't came. Is this normal? I normally have a 27-28 day cycle. I'm on CD (cycle day) 28 and 14 DPO. I'm going to buy a test later, but I'm stuck in the home until my package arrives I'm going nuts.
