Ovulation question

Hi ladies,

I need help. Yesterday morning I hit peak on the LH strips and I had a drop in temp. This has never happened to me before. I usually get a positive LH a couple of days before the dip. Can both occur on the same day? Do you ovulate after the dip or does the dip mean you ovulated? I know I have to wait for consecutive days of high temps to confirm, but I get a little confused as to when it actually happens.
