My periods have been 60-70 CD long have started taking vitex regularly then had a break as I went abroad and forgot it, for the past 4 weeks I have taken it twice daily and today I'm on cd14 and I have what appears to be signs of ovulation!!! I'm over the moon if it is as it will make my first cycle in 9/10 months a normal 28 day cycle but we shall see... wish me luck xx
