Yup - I've tried numerous times of the day, mostly around 5pm. It may be that I havn't Oed yet this cycle, even though I have some ferning on maybe baby. The ferns are only seen on parts of the microscope view so could be approaching O I guess. Also, this is my thrid cycle off BCP so that may have an impact on detection of LH in OPK (??). I will see what happens this afternoon as I've had 3 days of ferns in a row so +ve OPK could be yet to come!
Have you used maybe baby and got results with both this and OPK Tamara? If so, how many days did you get ferns and +OPK for?
