I just started taking ovulation tests again this month on Sunday. I used both the wondfo brand and clear blue opks. The wondfo was very light and the clear blue had a circle(not fertile).   But then yesterday I checked my CM and started having some left sided pelvic pain so I decided to test again with both. At 3pm the wondfo was much darker but not as dark as the control line and the clear blue showed PEAK fertility! What do you ladies think?? Has anyone used the wondfo opks and had success with them? I really do feel like I was ovulating yesterday just like the clear blue opk said! Any input would be greatly appreciated 😊
