I'm on CD20 and still haven't gotten a positive opk. There were two days where the test line was inbetween a light pink and the control line but never the exact matching color as the control line. I'm worried I somehow missed my surge and didn't get to BD enough to catch my O day. Plus, my cycles are very odd. They're sometimes very short, normal or very long. According to my doctor, my cycles are still considered normal. I just don't understand how they can still be normal. Here's a screen shot of my previous cycles in May and current cycle carrying onto today, June 1st. Can anyone relate?? This has been stressing me out. I'd like some feedback if possible, please.
