Not sure what this means , little help please & thank you ladies

So I was suppose to start my period the 4th , I had light cramps and back ache as if it was gonna show up since the 1st . I’m usually always right when I go to the bathroom thinking there is gonna be blood in the toilet after I get those pains .. since the day I was suppose to start I had little to nothing of brown spots on the toilet paper on and off .. it seems to only appear after I feel some light cramps .. I’m not sure when or if I ovulated cause I usually get really bad side ovulation pain but for some reason I didn’t get it this time ... I am now I guess 3 days late, cycle day 33... I did check my cervix to check if the blood was up there and nothing ... at this point I’m clueless and just waiting for it to drop ...does this sound like anything familiar to you ?
