Chart gurus?

Kim

Yesterday my two OPK , morning top afternoon bottom .. does it appear I may have ovulated last night instead of today as u can see from my attached chart I had a nice spike? I am on clomid First cycle had hideous ovulation pain on both sides yesterday but abdomen is still dull ache crampy today, the whole thung? Would that happen after ovulation ? We did BD yesterday afternoon and plan to this afternoon again .... just thoughts?
