Late peak opk ? Pregnancy sign?

I normally ovulate around a 14 or 15 and have 28 day cycles. Today is day 29 with no sign of AF.

I started testing for ovulation on day 9 and got several negative tests then I finally got my flashing smiley, however the flashing :-) lasted 10 days, it normally lasts one or two. I gave up I did not test yesterday or the day before. I was becoming so disappointed.

I've been cramping all morning and I had one ovulation test left, so I decided what the heck and used it. It finally came back with peak ovulation. Do you think it's really peak ovulation or could I be pregnant and that's what the test is picking up on?
