clear blue advanced ovulation test

Mo
Glow recommends first response and I'm wondering if that's because of a paid partnership or because fr is actually better than CB. I am on my second month using CB. My test goes from low to peak the very next day and back to low the third day. I don't get any "high" results. I'm wondering if it's because the test is not sensitive enough or if it's a problem with me. Any thoughts?
