Just wondering if anyone has experienced this. I have unexplained infertility-my periods are 28 days and really regular each month. Yet when I use ovulation test I don't get high or peak fertility. I have tried them pretty much constantly incase I am ovulating outside of the 'normal' period but nothing. My day 21 bloods indicated I was ovulating and came back normal. No sign of PCOS either as per Consultant. Also I'm using Clearblue Duel Hormone Kit. Have also tried cheaper ones but same results!
