opinions?

They say you'll get a dip before af but mines been in the steady 98s, do you think af will come? I am 6 days late but kee getting bfn. I was supposed to start on 3/3. Also when do you ladies think I actually ovulated? Because if you look at my chart I had two dip in temperature and two sets of positive opks so I have no idea how many DPO I actually am? I could of ovulated on CD 19 or CD 28 (which would make it hard to get pregnant because I have a 32 day cycle) One app says one think and one app says another
