Becoming frustrated

Hi ladies. So I got my IUD removed the middle of March and had a period 2 days later. Since then I have not had anything. Last month I got 11 days of high on clear blue advanced opks but no peak. I eventually gave up and figured I didn’t ovulate that cycle. I didn’t have a period last month either. Last Sunday I started getting highs again and I’ve also been using the cheapie opk test strips. My tests have basically looked like this ever since then. I test at least twice a day and have yet to get a positive. I’m getting super frustrated at this point. Anyone else have a similar experience? I’m worried I won’t ovulate again this month...
