Still no period after stopping the pill....

I Stopped taking my BC 5/13.. I was taking it straight through so i don’t know last period dates.. but still no signs of a period.. i remember before if i ever missed a pill I’d start bleeding right away.. I just want to figure out my cycle to give me some type of idea about ovulation predictions.. been taking ovulation tests also & had one that was slightly dark & since then they are all super light.. so confused, help!
