How come I’m having Ovulation Cramps and No LH surge yet?

I’m only Cycle day 12, I’ve had right sided sharp pain last night and now dull cramps in my lower abdomen intermittent today. I had spotting yesterday and EWCM. I feel like I should of had my surge by now! Anyone else have this happen and can you have ovulation cramps and not get a surge? I’ve heard when you have ovulation cramps that’s the pain you are feeling when the egg is being released.
