Any thoughts?

Please help I'm so confused. I had a very close +opk on May 30th I also had Ewcm in lots of stomach cramps. We BD'D the 29th and the 1st. I continues to test and was getting very faint to nothing lines on opks. However I took this about 15 minutes ago and this is what I got. I have almost no cervical mucus!! What is going on???? This closer to the time that flow says I should I but my periods have been a little irregular especially after my chemical pregnancy in April.
