Has anyone experienced this?

My last pill (clomid of course) was on 03/29/23. My predicted ovulation dates were

04/03-04/08. It's now the 5th, and I've yet to get a surge with my opk strip. On the 3rd, and 4th had very painful cramping. I mean, it was very painful. I'm talking lower abdominal region, in my backside, and etc. Today, at about 8:30 pm though... I started spotting. I am starting to think that l'm pretty much not going to ovulate this month. Then at the same time, I’m like I’ve 3 days. Anything can happen. Anyone else experience this? Did you end up ovulating? I’m taking 50 mg, and the fact that I have been experiencing side effects.. I want to believe it is working. However, who knows.
