cd 59 no sign of period or pregnancy

I am cycle day 59 and no signs of period- no cramping, no elevated bbt, no sore breasts. Also no sign of pregnancy- no sore breasts, no nausea, no darkened nipples or anything. I'm irregular but it hasn't taken this long before. I had two BFN in the past two weeks using dollar tree tests. I've started to feel a little dizzy past two weeks but only before bed and then I feel better. My stomach has been feeling odd and slightly painful but not anything serious. What's going on? Did I even ovulate? Has anyone had this and still tested positive?
